Methods for stool examination for rectal cancer

One of the important causes of colorectal cancer is a poor diet, which is characterized by a high intake of high-fat, high-protein, low-fiber foods. In layman's terms, this means a diet that is high in fish and low in vegetables. Therefore, if you eat more meat and less vegetables, you must be careful of colorectal cancer. Here is an introduction to the stool test for rectal cancer.

Many people do not do routine stool examination and digital rectal examination during physical examinations due to embarrassment and shyness. This is a huge misunderstanding. More than half of colorectal cancer patients in China have rectal cancer. Among rectal cancer patients, about 70% have mid-low rectal cancer, which can be detected by the doctor's touch. Stool occult blood in routine stool examination is a high-risk factor for colorectal cancer. If three consecutive stool occult blood tests are positive, indicating bleeding in the digestive tract, a colonoscopy must be performed.

There are three main ways to prevent colorectal cancer: 1. Diet adjustment. Reduce energy intake, reduce fat and red meat intake, increase fruits, vegetables and dietary fiber, and supplement vitamins and trace elements. 2. Quit drinking and smoking, and increase exercise. Weight loss and exercise can play a role in preventing colorectal cancer. 3. People with a personal or family history of colorectal cancer or adenoma have a higher risk of colorectal cancer and should be checked regularly.

The early symptoms of colorectal cancer generally include blood in the stool, changes in the time and frequency of bowel movements, abnormal stool shape, painful defecation, constipation or unexplained diarrhea, etc. The early symptoms are not very obvious, so they are easily ignored. Once discovered, it is already in the late stage. Therefore, it is very important to have regular physical examinations.
