About Colon Cancer

At Penn Medicine's Abramson Cancer Center, patients with colon cancer receive their care from a multidisciplinary team of nationally recognized experts in the diagnosis, treatment and research of gastrointestinal cancer.

The colon is the largest part of the large intestine, also known as the large bowel. After food is chewed and swallowed, it travels through the stomach and small intestine where it is broken down and most of the nutrients absorbed. It then passes to the large intestine where water and nutrients are absorbed from the food and waste matter is stored. The colon's function is to change liquid waste into solid waste and prepare it to be expelled from the body through the anus.

Colon cancer is the third most common type of cancer in both men and women, and is the second leading cause of death from cancer in the United States. Colon cancer is cancer that forms in the lining tissues of the colon. Most colon tumors begin when normal tissue forms a polyp, or pre-cancerous growth projecting from the wall of the colon. As the polyp grows, a tumor forms. Because the tumor grows slowly, early detection is possible through screening and tests.

Colon cancer is often combined with rectal cancer and can be referred to as “colorectal cancer.”

Penn Medicine's multidisciplinary approach to cancer diagnosis and treatment provides better outcomes and gives patients access to the most advanced treatment, surgical techniques and clinical trials.

Because navigating a cancer diagnosis and treatment options can be difficult, patients who wish to connect with a cancer specialist at Penn Medicine can speak with a cancer nurse, who can help them make an appointment with the right physician.
