How to discover clues of colorectal cancer

The early symptoms of colorectal cancer are not very obvious, and early detection of lesions is very important for the treatment of colorectal cancer. Because colorectal cancer is very easy to metastasize, if you seek medical treatment as soon as the early symptoms appear, you can improve the cure rate of colorectal cancer. The survival rate of early colorectal cancer within 5 years after surgery can reach 90%-95%, while the survival rate of late colorectal cancer is only 10%. Therefore, early detection of colorectal cancer is of great significance. How can we find clues of colorectal cancer? You can start from the following aspects.

First, high-risk conditions for colorectal cancer: ① Family history of colorectal cancer. Colorectal cancer refers to malignant tumors in the colon, rectum and anus. It is an autosomal dominant hereditary disease, especially for those whose parents both suffer from the disease. According to reports, about 1/8 of family cancer members or their offspring develop colorectal cancer. ② Family history of colorectal polyps. Polyps often occur in adolescence and can become cancerous after the age of 40. Therefore, once a patient is diagnosed with colorectal polyps, treatment should be started as soon as possible to prevent cancer. ③ For colorectal cancer patients who experience abdominal pain or abnormal bowel movements after surgery, colonoscopy should be performed in time to rule out the presence of multiple primary colorectal cancers. ④ A history of digestive tract tumors (such as gastric cancer) and breast cancer, etc. These tumors have the same cause as colorectal cancer.

Second, pay attention to the early symptoms of colorectal cancer: ① Unexplained changes in bowel habits are early manifestations of colorectal cancer. ② Changes in stool characteristics. ③ Middle-aged and elderly people with unexplained loss of appetite, fatigue and weight loss should be further examined. ④ Abdominal pain. ⑤ Blood in the stool. ⑥ Changes in temperament. In a few patients, irritability, irritability or depression may occur before the typical intestinal symptoms of colorectal cancer appear, or accompanied by poisoning symptoms after the disease. Their temperament changes are not specific.

Third, self-monitoring methods: ① Whether there is blood in the stool; ② Whether there is blood or mucus mixed in the stool; ③ Whether diarrhea and constipation occur alternately; ④ Whether the shape of the stool changes, such as the stool becomes thinner or flatter.
