Surgical Oncology - Colorectal cancers
Colon cancer is cancer of the large intestine, the lower part of your digestive system. Rectal cancer is cancer of the last 6 inches of the colon. Together, they're often referred to as colorectal cancers. Most cases of colon cancer begin as small, noncancerous polyps. Over time some of these polyps become colon cancers. Polyps may be small and produce few, if any, symptoms. Regular screening tests can help prevent colon cancer by identifying polyps before they become cancerous. Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they'll likely vary, depending on the cancer's size and location in your large intestine. These may include:
- A change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool for more than a couple of weeks
- Blood in your stool
- Abdominal discomfort, such as cramps, gas (bloating), or pain
- Abdominal pain with bowel movements
- A feeling that your bowels do not empty completely
- Weakness or fatigue
- Unintentional weight loss
