There are two main types of bowel cancer, rectal cancer and colon cancer. Cancer that occurs in the rectal area is called rectal cancer, but in a sense, the characteristics, differences and drug responses between rectal and colon cancer are not very significant. The development of bowel cancer from benign to malignant is a slow and continuous process, and some of this process is as long as 10 years. Early bowel cancer screening is very important. Early diagnosis of bowel cancer lesions mainly includes rectal finger examination and colonoscopy, and if bowel tumor is benign in early examination, there are more treatment options and better recovery after surgery. If the lesion is found in benign tumor stage, after treatment, the five-year survival rate is basically up to 100% or even cured. If it is a malignant tumor, it indicates to a certain extent that the long cancer cells in the body have metastasized and proliferated to different degrees. The five-year survival rate varies greatly among different stages, and the five-year survival rate of patients with serious conditions may even be less than 5%. What are the prevention means of bowel cancer? A good lifestyle can effectively prevent bowel cancer. What scientific habits should we pay attention to in our life? Both early diagnosis and early treatment of the disease can help patients prolong their survival rate. However, prevention of bowel cancer (i.e. prevention before it happens) is the best policy. Common preventive measures for bowel cancer are as follows: 1. More exercise, especially for white-collar workers, is one of the causes of bowel cancer, and the way to avoid sitting is to get up and walk. Exercise can increase the peristaltic capacity of the gastrointestinal tract, which can inhibit the growth of intestinal bacteria and prevent the emergence of rectal cancer and stomach cancer. 2, drink tea, tea polyphenols beneficial ingredients, antioxidant effect, but also to prevent the emergence of aging and cancer. Alcohol can increase the risk of cancer, especially frequent alcohol abuse. If you smoke at the same time, two cancer-causing factors will overlap with each other, and the risk of cancer will be increased. 4. Eat less meat and reduce fat intake. Usually, people who consume more fat will have higher body weight, and the probability of cancer is generally higher than normal people. Eat more soy-based foods, such as soy milk, milk and dried beans, which contain natural anti-cancer substances and can prevent many diseases and cancers.
