The situation of rectal cancer will directly affect the absorption of nutrition, and many patients with rectal cancer, due to insufficient absorption of nutrition, will lead to a variety of nutrients, trace elements and other deficiencies, not only the body is getting weaker, but also due to the lack of nutrition, so how long can rectal cancer live? Rectal cancer is a common cancer disease, which can lead to death or physical deterioration of many people, but if it is in the early stage of rectal cancer, with proper treatment, the survival rate is longer. The survival rate is also different because of different treatment choices. In the case of early stage rectal cancer, if the patient can slowly eliminate the cancer cells through targeted treatment and certain inhibition of the cancer, the patient can be completely free from the cancer cells and live for decades without much problem. In the case of early stage of rectal cancer, if the patient does not pay attention to it or does not pay enough attention to it, the rectal cancer will slowly deteriorate, thus causing the cancer cells to spread, in which case, it is possible for the patient to live for three to five years. Therefore, not every patient with early stage of rectal cancer can live as long. Therefore, if you know that early stage rectal cancer can be cured through treatment and can live for decades like normal people, you should treat yourself in time after you find out you have rectal cancer so that you can live longer. However, if some patients are not treated in time or without effective treatment, they may only live for three to five years. Five high-risk symptoms need to be alerted to intestinal tumors There are various kinds of anorectal diseases with different severity. Blood in stool, anal pain, anal swelling prolapse, anal drop and unformed stool are all common symptoms of anorectal diseases. In particular, the following 5 types of symptoms are very likely to hide colorectal malignant changes and are high-risk symptoms of rectal cancer: Symptom 1: Blood in stool It often manifests as blood on the surface of stool (especially painless blood in stool) with dark red or bright red color, which is easy to confuse hemorrhoids with rectal polyps or colorectal tumors and other diseases. Symptom 2: Anal pain In early stage of rectal cancer, the pain is not obvious or has hidden pain. In case of anal canal tumor, because of the sensitive nerves in the anal canal, pain can appear at the early stage of the tumor, and the pain is aggravated when defecating. Symptom 3: Anal mass prolapse refers to the mass bulging from the anal edge or the mass in the anal canal and rectum prolapsing out of the anus, some of them prolapse during defecation and can be incorporated into the anus by themselves after defecation; some cannot be incorporated after defecation or often prolapse out of the anus by themselves.
