Bowel cancer may show itching symptoms in early stage, but there is no such term as specific three itchy places. Some patients with bowel cancer may have itching around the anus or skin in the early stage, but this cannot be used as a criterion for diagnosing bowel cancer. Besides, the symptoms of early stage of bowel cancer are not very obvious, and with the development of the disease, it may attract the attention of patients themselves only when it reaches middle or late stage. Early stage of bowel cancer may include indigestion, diarrhea and change of stool characteristics, such as mucus-purulent stool and thin stool shape. Abdominal pain may also appear, which is often aggravated after eating spicy and greasy food. The above symptoms are usually not easy to attract attention. As the disease progresses over time, the symptoms may slowly worsen, such as blood in stool, weight loss, anemia, etc. If metastasis occurs in late stage of cancer, it may lead to dysfunction of liver and lung, and may be accompanied by jaundice, difficulty in breathing and different degrees of itching of skin. And at this time, if the tumor site is in the anal canal, itching around the anus may occur due to blood oozing from the erosion or secretion of more mucus to stimulate the skin. Generally, itching in cancer patients may be caused by tumor cells producing histamine, proteolytic enzymes and other substances, which stimulate skin sensory nerve endings. Therefore, if you have symptoms of itching, you should go to the doctor promptly and do not diagnose yourself to avoid delaying the treatment. In addition, if bowel cancer is diagnosed, early stage bowel cancer patients can be treated by surgical resection plus lymph node dissection, and the survival rate of patients with stage I bowel cancer can reach more than 90% in 5 years through early surgical treatment, and most patients can even be cured. Early detection and early treatment have better prognosis. In daily life, patients with early stage bowel cancer should avoid overexertion, cold and other conditions, and they can take appropriate exercise according to their specific conditions, such as walking, yoga and so on, and at the same time take appropriate high quality protein, such as eggs and milk, in order to promote recovery.
