Digital anal examination can detect early rectal cancer

70% to 80% of intestinal malignancies occur in the rectum, anal canal, and the junction of the rectum and sigmoid colon. Most rectal cancers occur in the lower 2/3 of the rectum, within 10 cm from the anal verge. Rectal cancer seriously affects people's quality of life and health, so it is very important to prevent rectal cancer.

Digital rectal examination refers to a method in which a doctor inserts a sterile gloved finger into the patient's anus to detect diseases. It is a simple but very important detection method.

In the early stage of rectal cancer, the lesions are limited to the intestinal mucosa, and the patient may not have any discomfort. The doctor can feel a slightly raised nodule during the examination. As the cancer progresses, the intestine may become infected and ulcerated, and then the patient will experience typical symptoms such as blood in the stool and constipation. It can be seen that rectal digital examination is very necessary, and regular inspection can effectively prevent the occurrence of rectal cancer.

80% of cancers can be found in this simple, non-invasive digital rectal examination. Various foreign bodies can be felt in the hand, such as hard, immobile nodular masses or pedunculated, movable polyp-like masses. If these foreign bodies are found and treated early, the risk of rectal cancer can also be reduced.

In short, rectal digital examination can detect intestinal abnormalities at an early stage and effectively prevent the occurrence of intestinal tumors.
