Colorectal cancer is malignant cells found in the colon or rectum. The colon and the rectum are part of the large intestine in the digestive system. Colon and rectal cancers share common features and are often called colorectal cancer. Cancerous tumors found in the colon or rectum may also spread to other parts of the body. Excluding skin cancers, colorectal cancer is the second most common cancer in both men and women.
People who have any of the following symptoms should check with their doctors, especially if they are over 50 years old or have a personal or family history of colorectal cancer:
- A change in bowel habits such as diarrhea, constipation or narrowing of the stool that lasts for more than a few days
- Rectal bleeding, dark stools or blood in the stool
- Cramping or gnawing stomach pain
- Decreased appetite
- Weight loss
- Weakness and fatigue
The symptoms of colorectal cancer may resemble other conditions, such as infections, hemorrhoids and inflammatory bowel disease. It is also possible to have colon cancer and not have any symptoms. Always consult your doctor for a diagnosis.
