What are the signs of "defecation", indicating that it is possible to suffer from intestinal cancer?

Under normal circumstances, if you have an unhealthy diet or catch a cold, you will have symptoms of diarrhea. However, if you don't catch a cold or diarrhea because of unhealthy diet, you should consider gastrointestinal diseases. Diarrhea lasts for a long time and is watery, so we should be alert to the possibility of colorectal cancer. Smell in the stool Although normal stools will smell bad, if the odor in the stool caused by colorectal cancer is different from that in normal stools, then the odor caused by colorectal cancer is generally fishy. These odors are mainly caused by intestinal bleeding caused by colorectal cancer and blood accumulation and digestion in the intestine. Abnormal stool characteristics Generally speaking, the shape of stool is mostly cylindrical, and it will be vertical downward when defecating.

However, the stool of patients with colorectal cancer will change in shape, and it will be thin or flat because it is squeezed by an oversized tumor. The normal stool color is mostly yellow or brown, and sometimes the stool color may change temporarily because of the pigment in the food. However, if the stool is dark or dark red, it may be related to colorectal cancer. Dry stool Generally speaking, the stool is wet and easy to discharge. Occasionally there will be dryness when constipation occurs, but this is normal. However, if you have colorectal cancer, the stool will be dry and granular, and it will be difficult to defecate, which will lead to long-term constipation. When the above-mentioned abnormal defecation occurs, the possibility of colorectal cancer is very high, and it is recommended to check it in time.

after the examination is clear, it can be treated by the following methods: drugs for this disease are bevacizumab and cetuximab. The former can combine with vascular endothelial growth factor, and then inhibit the proliferation of vascular endothelium and the formation of new blood vessels in tumors, reduce the nutrients needed by tumor tissues, and then achieve the purpose of inhibiting tumor growth. The latter can block intracellular signal transmission by binding with epidermal growth factor receptor, thus inhibiting cell proliferation and inducing apoptosis. Surgery is the main treatment for this disease, and early patients can be cured by surgery. In the middle and late stage, the tumor can be removed by surgery, supplemented by radiotherapy and chemotherapy, which can achieve good results. In addition, some patients with distant metastasis should also undergo surgery.
