Colorectal Cancer

Cancer of the colon, rectum, appendix and anus — known as colorectal cancer — develops in the tissues of the large intestine. This group of cancers is the second leading cause of cancer-related deaths in the United States and affects men and women equally. Fortunately, with screening, the majority of colorectal cancers can be prevented or detected while still treatable.

At the UCSF Helen Diller Family Comprehensive Cancer Center, our specialists are leaders in the diagnosis and treatment of colon, rectal and anal cancer. Our Center for Colorectal Surgery specializes in the treatment of colorectal diseases and offers the latest surgical approaches.

The Clinical Colorectal Cancer Research Program studies the epidemiology, prevention and early detection of these cancers. One of the primary objectives of the program is to determine the historical, environmental, dietary and genetic factors as well as the biological markers of patients at high risk of developing colorectal cancer.
