Colorectal cancer in women: an equal opportunity disease.

Colorectal cancer is the second leading cause of cancer-related deaths in developed countries. For women, it is the third leading cause of cancer-related deaths behind lung and breast cancers. Women have the same risk as men, and the lifetime risk of the development of colorectal cancer is 6%. One in 17 woman will have colorectal cancer diagnosed. There are risk factors unique to women, including gynecologic cancers, and treatment of gynecologic cancers, as well as delayed diagnosis in pregnancy. Fortunately, colorectal cancer is a preventable disease, as almost all colorectal cancers arise from premalignant polyps. Colorectal cancer screening is recommended in asymptomatic women aged 50 years and older who are at average risk. Screening and surveillance for colorectal cancer in women are important to improve the morbidity and mortality rates of this preventable disease.
