What are the early symptoms of colon cancer

The colon starts from the cecum and ends at the rectum. It is frame-shaped in the abdominal cavity and can be divided into four parts from right to left: the ascending colon, transverse colon, descending colon and sigmoid colon. The colon mucosa is prone to cancer. With the improvement of living standards, the proportion of animal food in the diet has increased, and the incidence of colon cancer has also been increasing. The main function of the colon is to form stool, so the early symptoms of colon cancer are often manifested as changes in the nature of stool and bowel habits.

The so-called change in bowel habits means that compared with the patient's original bowel habits, the frequency, time and nature of bowel movements have changed. Excluding factors such as diet, colon inflammation, and abnormal colon function, this is often one of the early symptoms of colon cancer, especially for middle-aged and elderly people who have increasingly severe changes in bowel habits for no apparent reason. Generally speaking, right-sided colon cancer is prone to diarrhea, while left-sided colon cancer is prone to constipation and abdominal distension.

Another early symptom of colon cancer is blood in the stool, which is caused by damage or ulceration on the surface of the lesion. When bleeding occurs in the right colon cancer, the blood is mixed with the stool. If the amount of bleeding is small, only the occult blood test is positive and the blood cannot be seen with the naked eye. When bleeding occurs in the left colon cancer, the blood often adheres to the surface of the stool because the left colon is closer to the anus and the stool has already formed. If the amount of bleeding is large, purple or bright red blood can be seen at a glance; if the amount of bleeding is small, red blood cells can be found in the stool test.

Once the above-mentioned early signs of colon cancer appear, you should take the time to do fiber colonoscopy, because fiber colonoscopy can not only directly see the lesions, but also can immediately biopsy, and confirm or exclude colon cancer through pathological sections. Some people are afraid of fiber colonoscopy and are willing to choose barium enema examination, which can certainly detect colon cancer, but it cannot be diagnosed because cancerous tissue cannot be obtained. A comprehensive and detailed examination can detect cancer as early as possible. Clinically, when patients see blood on feces, they become alert and go to the hospital for examination. Cancer cells are finally found and confirmed to be early colon cancer. After treatment, he has survived for 6 years. This is attributed to the patient's own health awareness and the correct measures of early detection, early diagnosis, and early treatment.

The above are the early symptoms of colon cancer.
