Colon cancer is the 2nd leading cause of cancer death among men and women combined in the United States.

In 2017, it’s estimated there will be 135,430 new cases and 50,260 deaths from colon and rectal cancers.

  • 1 in 20 people will be diagnosed with colorectal cancer.
  • 1 in 3 people are not up-to-date with colorectal cancer screening.
  • 25% of people diagnosed with colorectal cancer have a family history.

Rates of colorectal cancer for people under age 50 have risen, particularly for rectal cancer.

Colon cancer happens when tumorous growths develop in the large intestine. It is the third most common type of cancer in the United States.

However, advances in diagnosis, screening, and treatment have led to steady improvements in survival.

Colon cancer happens when out-of-control cell growth occurs in the large intestine.

Most colon cancer originates from noncancerous, or benign, tumors called adenomatous polyps that form on the inner walls of the large intestine.

Cancerous cells may spread from malignant tumors to other parts of the body through the blood and lymph systems. These cancer cells can grow and invade healthy tissue nearby and throughout the body, in a process called metastasis. The result is a more serious, less treatable condition.
