The rectum is the final section of the intestine, located right next to the anus. Therefore, you can often detect rectal health problems through unusual symptoms around the anal area.

Below are some warning signs that may help you recognize rectal cancer early and take timely preventive measures.

Anal bleeding

One of the most noticeable symptoms of rectal cancer is bleeding from the anus during bowel movements. When stool passes through tumors, they not only cause pain but also burning and bleeding in that area. For this reason, frequent anal bleeding could be an early sign of the disease.

Passing thin stools

If you notice that your stools are consistently thin, it could also be a warning sign of rectal cancer. This happens because obstructions in the bowel alter the shape of the waste as it moves through. These obstructions are often swollen tumors forming at the end of the colon.

Unusual anal discharge

When abnormal discharge occurs from the anus, it usually indicates that rectal cancer has advanced to a more severe stage. This happens when large tumors press on surrounding blood vessels, causing fluid to accumulate in the area. Eventually, this fluid finds its way out through the anus, leading to discharge.

Frequent vomiting



Tumors in the rectum can press against surrounding organs, disrupting the digestive system and leading to vomiting. This symptom often occurs when the tumor grows large enough to put pressure on other parts of the abdominal cavity, causing discomfort throughout the abdomen.

Unexplained weight loss

Tumors in the large intestine can also disrupt hormones and other bodily functions, resulting in unexpected health issues. Weight changes, in particular, are closely linked to rectal tumors. Therefore, if you experience unusual weight loss without dieting or trying to lose weight, you should seek medical attention to determine whether it may be rectal cancer or another form of cancer.
