Risk Communication: Information for the Clinician about Colorectal Cancer Risk

Colorectal cancer is the third most common cancer in both men and women and the second leading cause of cancer mortality. Only prostate and lung cancer in men, and breast and lung cancer in women, are more common.  The American Cancer Society estimates that there will be 148,810 new cases of colorectal cancer and 49,960 deaths from CRC in 2008 in the United States.

CRC has received widespread public attention in recent years.  A number of celebrities have shared their diagnoses or discussed screening with the public.  Awareness of CRC is important for three major reasons.

• Colorectal cancer is detectable by several screening modalities.

• Detection at an early stage has a substantial impact on survival.

• Risk can be modified by attention to medical history and lifestyle choices.
