About Colorectal Cancer

Colorectal cancer is cancer that develops in the colon or the rectum. In the United States, colorectal cancer is the third most diagnosed cancer in both men and women, and the second leading cause of death from a cancer.

Most cases of colon cancer begin as small, noncancerous clumps of cells called polyps. Over time some of these polyps become colon cancers.

Polyps can be small and not show any symptoms. For this reason, doctors recommend regular screening tests, such as colonoscopies.

Screening colonoscopies may even prevent disease if pre-cancerous polyps are discovered and removed.
