Types of colorectal cancer

There are two types of colorectal cancer: colon cancer and rectal cancer. Colon cancer is found in the large intestine and the lower part of the digestive system. Rectal cancer is found in the last several inches of the colon.

Most colon cancers start as benign clumps of cells found in the colon called adenomatous polyps. Over time, some of these polyps can become colon cancer. The vast majority of polyps are small and rarely produce any symptoms. Doctors recommend regular screenings, including colonoscopies, to help prevent colon cancer by identifying polyps before they become cancerous.

There are very few warning signs of colon cancer during the early stages of the disease. As the cancer spreads, symptoms are more likely to appear and will vary depending on the size and location of the cancerous cells.

Colorectal cancer symptoms

Some of the symptoms associated with colorectal cancer include:

  • Unexplained weight loss
  • Bloody stool
  • Inconsistency in bowel habits, including diarrhea or constipation
  • Abdominal discomfort that lasts for more than a few days

Colorectal cancer treatment

If you’ve been diagnosed with colorectal cancer, your cancer care team will discuss your treatment options with you. Your treatment depends on what stage your cancer is currently in and can consist of one or more of the following:

  • Surgery
  • Chemotherapy
  • Radiation therapy
  • Medications
