Selenium
Selenium is a trace mineral in the human diet. There is also little knowledge in society about the impact of this element on human health. It is definitely not as popular as magnesium or zinc, although it is equally necessary in our diet. Humanity became aware of the existence of selenium over two centuries ago, when it was isolated by the Swedish chemist Jacob Brezelius. What more do we know about him now? First of all, it is an essential component of enzymes involved in oxidation-reduction processes and cytochrome, thanks to which it protects cell membranes, and therefore the cells themselves, against oxidative stress. Hence its beneficial effect on the immune system. People suffering from any thyroid disorder have certainly come across information about its key role in the metabolism of this gland's hormones. The problem of male infertility allowed us to draw attention to the role of selenium in proper spermatogenesis, where this ingredient is necessary for the formation of sperm with proper structure and the desired motility. Less known properties of selenium include its influence on the proper functioning of the muscular system, including the heart muscle. They are so important that in regions of the world exposed to extreme deficiencies of this element, we are dealing with a specific cardiomyopathy (Keshan disease). We will also find information confirming the impact on the low birth weight of newborns whose mothers were deficient in this microelement. There are interesting reports about the effect of selenium on the nervous system, where deficiencies manifest themselves in mood declines. And finally, related to the antioxidant effect, it influences the development/inhibition of some cancer diseases, e.g. prostate, lung or colon cancer. Selenium deficiency may manifest itself through: - hair loss and brittle nails, - nervous system disorders (low mood, depression), - fatigue, - weakness of skeletal muscles and heart muscle, - weakened immunity, - thyroid abnormalities, - male fertility disorders. Where to look for selenium? The element is taken from the soil by plants, which become food for herbivorous animals. Theoretically, both animal and plant food can be its source. Foods recommended for deficiencies are most often: offal (kidneys), eggs, dairy products, sea fish, mushrooms, garlic and Brazil nuts. The latter, generally considered to be the richest source, obviously do not come from our region, and when buying them we may not be 100% sure whether they actually come from areas rich in this element. In practice, in Polish latitude, we deal with low selenium content in the soil, which results from the geographical location. The rocks from which the soil is formed in our native areas are very low in selenium. Additionally, the acidic nature of these soils makes it difficult for plants to absorb the said mineral. Supplementation may be the solution to replenish the deficiencies. The preparations available on the market include both organic forms (l-selenomethionine) and inorganic forms, e.g. sodium selenate. The daily recommended intake of selenium for adults is 55 mcg. However, supplements may contain a dose almost four times higher, up to 200 mcg. When supplementing selenium, it is worth remembering that it is a trace element for humans, which means that there is a small difference between a therapeutic and toxic dose. Therefore, despite potential deficiencies, when deciding on supplementation, it should be used very carefully, in accordance with the dictum of Paracelsus Everything is poison and nothing is poison. Only the dose makes a substance not a poison.

Medicine or dietary supplement? What to choose?
Mr. Magister, I would like some magnesium "in the form of a MEDICINE". A conversation at the pharmacy window often begins with this phrase. Then the patient begins a long analysis of the composition and packaging to be 100% sure that there is no inscription "dietary supplement" on it. The pharmacist often avoids talking about this topic, but should still be prepared to talk to the patient. The problem of distinguishing and comparing drugs and dietary supplements is quite difficult. Both product categories are placed on adjacent stands and have similar, and often the same, composition. So what is the mystery and why do patients try so hard to buy a drug and not a dietary supplement? Let's start with individual definitions. A medicinal product is a substance or mixture of substances presented as having properties for the prevention or treatment of diseases occurring in humans or animals or administered for the purpose of making a diagnosis or for the purpose of restoring, improving or modifying the physiological functions of the body through pharmacological, immunological or metabolic action. (Pharmaceutical Law of September 6, 2001, Chapter 1 Art.2 Point 32.) The definition contained in the Act clearly states that a drug (medicinal product) prevents, cures, improves or modifies the physiological functions of the body. Whereas: Dietary supplement - a food intended to supplement a normal diet, being a concentrated source of vitamins or minerals or other substances having a nutritional or other physiological effect, single or combined, placed on the market in a form enabling dosing, in the form of: capsules, tablets, dragees and in other similar forms, sachets with powder, ampoules with liquid, dropper bottles and other similar forms of liquids and powders intended for consumption in small, measured unit quantities, excluding products having the properties of a medicinal product within the meaning of the provisions of pharmaceutical law. (UST AWA of August 25, 2006 on food and nutrition safety, SECTION I, Art. 3 point 3, ppk39) According to this definition, a dietary supplement is a food that is intended to supplement the normal diet with vitamins, minerals and "other" substances. At first glance you can see the difference, but is it really? Looking at the last part of the definition: excluding products with the properties of a medicinal product within the meaning of pharmaceutical law, we reach the point where it is impossible to distinguish a dietary supplement from a drug. What is the difference between a medicinal product containing 2000 IU of vitamin D3 in the form of cholecalciferol and a dietary supplement containing exactly the same in the same form, but in capsules? There are several differences between a drug and a dietary supplement, but neither side achieves a clear competitive advantage. The first issue concerns legal aspects. Various institutions register both product groups. Drug registration is handled by URL (Drug Registration Office). It does this on the basis of many tests and certificates. However, the Chief Pharmaceutical Inspector is responsible for marketing authorization in the country. Dietary supplements are also officially registered by the Chief Sanitary Inspector (GIS) on the basis of an application submitted by the entrepreneur. Therefore, it is not the law that supplements are not subject to control, because the GIS may refuse to register or, in case of uncertainty, may ask for an opinion from the URL. The registration procedure for dietary supplements is shorter and easier to carry out, which is why many drug manufacturers register their next products in this category. The second thing is the doses of individual ingredients. Based on the dose definitions, substances in a drug have a curative or preventive effect, while in a supplement they have a nutritional effect. No less surprising is the fact of the existence of vitamin C - a drug in doses of 200 and 500 mg in the presence of the same vitamin - a supplement in doses of 1000 and 2000 mg. Questions arise about the body's actual needs, the dose that produces a therapeutic or nutritional effect, and the dose that is too high to be safe. Another aspect concerns the origin of the ingredients contained in the products. Due to high standardization requirements and the purity of substances, synthetic substances obtained through chemical reactions are often used in medicinal products. Dietary supplements often contain ingredients of natural origin, which seems to be a healthier solution and more adapted to the living organism. They also contain plant ingredients and their extracts. Sometimes dietary supplements contain plant ingredients that are not found in our climate or in Europe, but which have a proven positive effect on health and fitness. Further differences concern promotion and advertising. No elements of the packaging, names or advertising of supplements may suggest medicinal properties. Each package must also have the description "DIETARY SUPPLEMENT". Every day we are attacked by advertisements for medicines and supplements, so much so that it is difficult to know what and whether it is worth buying to support our health. We consume large amounts of medicines and dietary supplements every day. This is due to the fact that the availability of supplements is very high, advertising in the media is intense, and society is taught to respond to changes in its health by purchasing new preparations. Supplements are used to improve the condition of hair, nails, skin, eyes, joints, etc. We supplement vitamins, minerals and herbs using multi-ingredient products. Therefore, it is important to know the exact composition of a given preparation. There is a high probability that several preparations will contain the same ingredients and by taking a whole range of products we will provide too high doses of the mentioned vitamins or minerals. It is also worth remembering that the most important source of supplementation is food, i.e. what we eat. So how should you approach the use of supplements to make it safe? Let us remember that choosing a drug as a safe form will not always meet the nutritional and health needs of the body. On the other hand, not all supplement manufacturers meet the quality standards of their products. Taking this summary into account, you should follow a few rules to achieve the appropriate nutritional effect while maintaining safety. Here are the rules worth following Let's choose high-end supplements - there are several leading companies on the market. Some of them can be found on our website. Companies with extensive experience, certified products and production standards such as GMP, ISO, etc. The most advantageous offers are provided by companies that grow medicinal herbs themselves and produce vitamin and mineral ingredients instead of mass purchases from suppliers. Let's use only those substances that we need - it's best to discuss the selection of ingredients with a specialist. Do not use supplements recommended by third parties. The appropriate selection of supplements in oncological diseases and post-oncological therapies is extremely important. Many ingredients have the ability to stimulate excessive cell growth. If possible, use single-component or multi-component preparations. We will then avoid the possibility of duplicating doses of the same substance. Let's ask a specialist when and how to take a given product. Often, the absorption of the substance and the effect of the entire preparation depend on the time of day or the meal we take. In light of these assumptions, I believe that the use of dietary supplements can be safe and bring good results. By choosing only medicinal products, we will not achieve long-term effects and visible results. A well-balanced and well-thought-out combination of medicine and dietary supplement can achieve very good results. Let's take the medicines that are necessary for us, let's take the dietary supplements that we need, but let's not forget about proper nutritious food, including fruit and vegetables.

When is it worth visiting a gastroenterologist?
Digestive health plays a key role in an individual's overall health. Our digestive system is not only responsible for the absorption of nutrients, but also plays an important role in the immune system and metabolism. However, its improper functioning can lead to a variety of health problems. Therefore, understanding the importance of digestive health and being aware of signals that may indicate the need to consult a gastroenterologist are extremely important for maintaining full health and well-being. Symptoms that may indicate the need to visit a gastroenterologist are usually related to gastrointestinal problems and can be diverse. Among them stand out: Abdominal pain, which may occur in various places and have a different nature (dull, stabbing, cramping). If the pain persists for a long time or occurs regularly, it may be a sign that there is a problem in the digestive system that requires evaluation by a specialist. Heartburn, i.e. burning or burning sensation in the esophagus and chest area. Its frequent occurrence may indicate gastroesophageal reflux disease, i.e. the reflux of stomach contents into the esophagus, leading to damage to the mucous membrane. Recurrent damage and inflammation predispose to cancer processes, therefore faster diagnosis and initiation of treatment are associated with a better prognosis. Bloating, nausea, vomiting, diarrhea or constipation may indicate various conditions such as irritable bowel syndrome, inflammatory bowel disease, intestinal infections or other digestive disorders. Sudden and unintentional weight loss. If you noticeably lose weight despite maintaining a normal appetite and a healthy lifestyle, this may be a reason to consult a gastroenterologist. Weight loss can be caused by various digestive disorders, such as inflammatory bowel disease, celiac disease, colon cancer or other serious disorders, but cancer can also be the cause. Changes in stool consistency may be an important signal of health problems other than cancer. If continuous diarrhea or constipation is observed, as well as changes in the color, consistency or appearance of the stool, consultation with a gastroenterologist is recommended. This may suggest not cancer but problems such as irritable bowel syndrome, Crohn's disease, ulcerative colitis or other diseases that require diagnosis in a doctor's office. Prevalence of cancer of the digestive system in the family. Separate recommendations for such patients are currently in force and are still being developed. These most often include suggestions for accelerated tests detecting early signals of these diseases and performing an extended panel of genetic tests. Therefore, the presence of cancer or autoimmune diseases in the family should prompt other relatives to take appropriate preventive measures and monitor their health. Environmental factors such as diet, lifestyle, stress factors and infections also play an important role in the occurrence of digestive system cancers. Eating habits and lifestyles may be similar within families, contributing to a similar environment that may promote the development of these conditions. Regular examinations and practicing healthy eating and lifestyle habits can help prevent or detect these diseases early. ATTENTION! If any symptoms occur, it is extremely important not to delay visiting a gastroenterologist. Early recognition and treatment of serious digestive problems, including cancer, can be crucial to continuing to lead a healthy life. Adam Trzciński

The role of physiotherapy in reducing inflammation in patients
Physiotherapy, as an integral part of medical rehabilitation, plays a key role in managing inflammation in patients. Inflammation is often associated with a number of diseases, including rheumatoid arthritis and even cardiovascular disease. Physical therapy can help relieve symptoms and speed up the healing process. Mechanisms of action Physiotherapy uses various methods and techniques that help reduce inflammation, such as manual therapy, therapeutic exercises, heat and cold therapy, ultrasound and electrotherapy. These techniques are intended to reduce pain, improve mobility, increase muscle strength, and improve the overall performance of the body. Manual therapy Manual therapy, which includes massage and joint mobilization, helps reduce inflammation by improving circulation and reducing muscle tension. Improving circulation helps deliver nutrients to the inflamed area and speeds up the removal of waste products, which speeds up the healing process. Therapeutic exercises Therapeutic exercises are a key element of physiotherapy. They help maintain and improve range of motion, increase muscle strength and improve the overall performance of the body. Regular exercise can also help reduce inflammation by increasing the production of the body's natural pain-relieving and anti-inflammatory substances, such as endorphins. Heat and cold therapy Heat and cold therapy are often used to reduce inflammation. Heat helps increase blood circulation, which speeds up the healing process, while cold helps reduce pain and swelling. Electrotherapy and ultrasound Electrotherapy and ultrasound are other popular techniques used in physical therapy. Electrotherapy uses electrical current to stimulate nerves and muscles, which helps reduce pain and swelling. Ultrasound, by producing a sound wave, can help reduce inflammation by improving blood circulation and stimulating healing processes. Physiotherapy is therefore a key element in the treatment and management of inflammation. By using appropriate techniques, physiotherapy helps reduce pain and swelling, increases range of motion and improves patients' quality of life. However, it is important to remember that physical therapy is part of a comprehensive treatment plan and should be used in conjunction with other forms of therapy such as anti-inflammatories and lifestyle changes.

The role of physical activity in cancer prevention
Exercise can increase motivation to change lifestyle, improve aerobic capacity, improve physical fitness, control fatigue and improve quality of life [1], and this is just a part of their beneficial effects on the human body at all ages. It is estimated that almost half of cancer cases can be prevented by changing lifestyle, including physical activity [2], which is one of the four pillars of health. In a report by The World Cancer Research Fund (WCRF) published in 2020, the organization indicates that it plays a significant role in cancer prevention [3] . The main benefits of physical activity include regulating body weight, improving the efficiency of the circulatory and respiratory systems, as well as strengthening muscles and bones. Blood flow and tissue oxygenation are also increased, which translates into greater energy and vitality. Additionally, exercise has a real impact on mental health because regular exercise can reduce symptoms of depression, anxiety and stress by releasing hormones that can improve mood and feelings of overall well-being. Physical activity also improves cognitive functions, i.e. memory, concentration and the ability to focus, and significantly increases the quality of sleep by regulating the circadian rhythm. Regular exercise can help you fall asleep faster and enable deeper sleep, and it also lowers blood pressure, reducing the risk of heart disease. The multi-year European Prospective Investigation into Cancer and Nutrition (EPIC) study of over 500,000 people found that regular physical activity was associated with a lower risk of many types of cancer, such as colorectal cancer, breast cancer, pancreas and endometrial cancer [4]. A meta-analysis based on 170 studies confirmed that regular physical activity is associated with a reduced risk of colorectal cancer. It was observed that people engaging in regular physical exercise had a 24% lower risk of developing this type of cancer compared to people leading a sedentary lifestyle [5]. A study published in the British Journal of Cancer and conducted by the European Prospective Investigation into Cancer and Nutrition - EPIC found that regular physical activity can reduce the risk of breast cancer in postmenopausal women. Women who performed at least 7 hours of moderate physical activity per week had a 13% lower risk of developing breast cancer compared to those who were physically inactive [6]. Systematic physical activity, which can be freely chosen from a wide range of possibilities, from walks in nature, through team games, to individual training in the gym, provides great support in cancer prevention. It is a permanent element of a healthy lifestyle, which is modified depending on possibilities, needs and preferences. In addition to the obvious physical benefits it brings, it has a real impact on improving mood and well-being. Its beneficial effect on the body is multidimensional, so it is worth including it permanently in your weekly plan.

Needs in cancer patients - how to communicate them?
Communication regarding sexual needs in cancer patients is important, but unfortunately often overlooked. There is a false belief that, given the many challenges that cancer brings to a patient, sexuality is one of the last things that should be taken into account. This is absolutely not true - sexual needs are physiological needs and, just like any other, they require satisfaction. Of course, in the course of oncological disease, the possibilities of satisfying sexual needs may (but do not have to) be slightly modified, but this does not mean that the patient's sexual life ceases to be a source of fulfillment and satisfaction [1] . The treatment team has an important role in the process of caring for the well-being of an oncology patient. First of all, it is good practice to create a safe and trusted environment for the patient. The patient should feel comfortable and safe because this is what creates space to open conversations about sexual needs. It is important for the doctor to create an atmosphere of trust so that the patient knows that he is welcome to express his concerns and ask questions about sexuality. It is also good practice for the doctor to initiate a conversation about sexual needs. During such a conversation, it is worth assuring the patient that it is natural to have questions or concerns about the impact of the disease and oncological treatment on the sexual sphere. Open questions will certainly be helpful in such a conversation, as they will allow the patient to express his concerns or describe new experiences [2] . Proactivity is also important - listening carefully to the patient. This creates space to express your emotions, concerns and questions. At this point, it is worth paying attention to how important it is to listen carefully and show interest and understanding. The next step is to provide the patient with the necessary information about possible side effects of treatment, changes in sexual function, and available strategies and resources that can help deal with these challenges. In providing comprehensive care, the cooperation of the entire treatment team is crucial - many different fields of medicine may influence the sexual needs of oncology patients. Patient care can be provided not only by doctors and nurses, but also by psychologists and sexologists and psychotherapists. It is important to provide the patient with comprehensive care to be aware of problems arising during treatment, because this allows the patient to be referred to the appropriate specialist if necessary [3] . Your own work also plays an invaluable role - it is worth encouraging the patient to seek support - your doctor can inform you about available resources and support groups for cancer patients. Self-help groups can be valuable support in dealing with challenges in meeting sexual needs. Support can be received either through individual therapy, through group therapy sessions, or through use from extensive resources conveniently available electronically.

The impact of cancer on sexuality
Cancer can have a very diverse impact on a person's sexuality. It depends on many factors, including the type and stage of the disease, the type of treatment used and the individual characteristics of the patient and psychological support - both from specialists and the patient's relatives. Cancer may affect physical and hormonal changes in the body, decreased energy, chronic fatigue, changes in appearance, stress, emotional changes or self-esteem, body image and interpersonal relationships. All the areas indicated above may have a greater or lesser impact on sexuality. Some types of cancer and treatments can lead to physical changes that may affect sexual function. They can, but they don't have to - remember that each case is different, so generalizations are subject to a large margin of error. However, to use specific examples, surgery to remove genital organs may have a significant impact on experiences related to sexuality. Other treatments - such as radiotherapy (especially in the genital area) or chemotherapy - may be equally important and may result in pain, vaginal dryness or erection problems. The desire and appetite for physical intimacy and sex may also decrease [1] . Some types of cancer and their treatment may affect hormone levels. Examples of treatments that influence hormonal changes include removal of the ovaries, surgical treatment of breast cancer or targeted hormonal therapy. This type of treatment may affect both the level of desire and sexual function [2] . Cancer and its treatment usually lead to decreased energy and increased fatigue. It is often accompanied by changes in appearance, such as weight loss, hair loss, or scars after surgery. It is worth remembering that sexuality has various dimensions and may also include building a sense of security and attractiveness. Sex is not prohibited for cancer patients - unless it is a cancer related to the reproductive organs. Undoubtedly, it may be difficult for loved ones to realize that a person suffering from cancer often feels unattractive and defective. The change in self-perception affects the feeling of increasing stress and deepening depression of mood. This is a difficult moment both for the sick person and for their loved ones. A person suffering from oncology has every right to closeness - it is worth talking about their needs and concerns [3] . It may be helpful to formulate messages as direct as possible - e.g. "you can touch me", "don't be afraid to touch me, it doesn't hurt me", "it's important to me, I want you to keep touching me", or "I want you to as little as possible has changed between us. I have to go to the doctor, I have to take medications, but let everything else be as it used to be, I need your touch as much as before (or even more than before).” Cancer may affect self-esteem, body image, interpersonal relationships, and perception of one's sexuality. Some patients may feel a sense of loss, fear of rejection, shame, difficulty communicating with a partner or difficulties in finding their way in a new reality after the diagnosis. It is important that patients talk to their doctors about all problems related to sexuality - there are various strategies, therapies and treatment methods that may be helpful in dealing with the new challenges presented by the disease. Many patients also use the help of psychologists, sexologists or patient support groups [4] . Problems related to sexuality affect the quality of life and should not be treated marginally. Sexual health is important, and when problems arise, it is worth contacting specialists and asking for help. Monika Kaszuba [1] Dębska G., Samochowiec J. (2017).

The importance of screening tests in detecting digestive system cancers
Digestive system cancers pose a serious threat to the health and life of patients around the world. Their early detection is crucial for effective treatment and improved prognosis. In this article, we will discuss the importance of screening tests in detecting digestive system cancers and present the most important screening methods used in medical practice. Screening tests aim to detect cancers at an early stage, when they do not cause symptoms or are non-specific. Thanks to this, there is a greater chance of effective treatment and improving the patient's prognosis. Here are some of the most important screening tests used to detect digestive system cancers: Colonoscopy One of the most effective screening tests for detecting colorectal cancer. It involves inserting a flexible endoscope through the anus, which allows visualization of the interior of the large intestine. During the examination, polyps can be detected, which can lead to colon cancer. If found, they may be removed during examination or samples taken for further histological evaluation. Test for the presence of occult blood in stool This test examines a stool sample for the presence of blood, which cannot be seen with the naked eye. The presence of occult blood may indicate the presence of polyps or tumors in the large intestine. A positive test result usually requires further diagnostics, such as a colonoscopy. Gastroscopy This is a test that allows visualization of the inside of the esophagus, stomach and upper section of the small intestine using a flexible endoscope inserted through the esophagus. Gastroscopy can help detect, for example, stomach cancer. During the examination, tissue samples may also be taken for further histological evaluation and biopsy specimens may be tested for Helicobacter pylori infection. Imaging examination Imaging such as computed tomography (CT) and magnetic resonance imaging (MRI) may be used to detect digestive system cancers such as pancreatic cancer. These techniques enable accurate visualization of internal organs and can help identify tumors, assess their size and distribution. The above imaging tests are accurate and objective, but their availability is limited. A more common solution is an ultrasound examination, which, although its accuracy depends on the skill of the person performing it, can serve as a preliminary screening test before qualifying for CT or MRI. Screening is recommended for people at increased risk of developing digestive system cancers, such as those with a family history of cancer, existing risk factors, or certain symptoms. Regular screening can help detect cancer at an early stage, which in turn increases the chance of effective treatment and improved prognosis. Therefore, it is clear that screening tests play a key role in detecting digestive system cancers at an early stage. Methods such as colonoscopy, fecal occult blood test, gastroscopy and imaging enable the identification of cancer lesions and polyps, which enables early treatment. People at increased risk should get screened regularly as recommended by their doctor. Public education and awareness of the importance of screening are crucial for the prevention and early detection of digestive system cancers. Adam Trzciński

The role of endoscopy in the diagnosis and treatment of gastrointestinal cancer
Gastrointestinal cancers constitute a serious health problem worldwide. Diagnosing them is extremely important to detect the disease early and provide patients with appropriate treatment. Nowadays, endoscopy plays a key role in the detection and treatment of gastrointestinal cancers. In this article, I will discuss the role of endoscopy in these areas from the perspective of a gastroenterologist. Endoscopy is a non-invasive diagnostic technique that allows direct viewing of the inside of the digestive tract. Using a flexible speculum (endoscope), the doctor can view the mucous membrane of the esophagus, stomach, small and large intestine. If cancer is suspected, endoscopy allows visualization of the tumor, assessment of its location, size, shape and characteristic features. Additionally, during endoscopy, tissue samples (biopsies) can be taken for histopathological examination, which allows confirming or excluding the presence of cancer. Endoscopy can also be used to detect pre-cancerous lesions, such as colon polyps, which can develop into full-fledged cancers. Removing these lesions during endoscopy (polypectomy) can prevent the development of cancer. Additionally, endoscopy can be used to assess the extent of the tumor and assess the infiltration into adjacent tissues and lymph nodes, which is necessary when planning treatment. Endoscopy also plays an important role in the treatment of gastrointestinal cancers. In some cases, when the cancer is early and limited to the mucosa or submucosa, it can be removed using endoscopic techniques. For example, for early-stage colorectal cancer, endoscopic techniques such as endoscopic submucosal resection (ESD) may be used. These procedures allow the tumor to be removed without the need for open surgery. Additionally, endoscopy can be used to insert prostheses to unblock narrowed sections of the digestive tract caused by developing cancer. These prostheses enable the proper flow of food and alleviate symptoms such as swallowing difficulties. After treatment for gastrointestinal cancers, endoscopy plays an important role in monitoring patients. Regular endoscopic check-ups allow you to assess the effectiveness of treatment, check for disease recurrence and detect any recurrence or complications early. To sum up - endoscopy is an extremely important diagnostic and therapeutic technique in the case of gastrointestinal cancers. Thanks to it, it is possible to detect the disease earlier, more precisely assess the extent of the tumor and its characteristic features, and provide effective treatment. Gastroenterologists play a key role in performing endoscopy, interpreting the results, and making appropriate therapeutic decisions to improve the patient's condition and combat gastrointestinal cancers.
