Breast cancer is a malignant proliferation of epithelial cells lining the ducts or lobules of the breast.  For women, the three most commonly diagnosed cancers are breast, lung, and colorectum, representing one-half of all cases; breast cancer alone is expected to account for 29% all new cancer diagnoses in women.  It is estimated that 252,710 cases of breast cancer will be diagnosed and 40,610 patients will die of the disease in the United States in 2017.

The incidence of cervical cancer in the US has decreased more than 50% since 1975.  Most of that decrease can be attributed to better screening practices.  This online module discusses current guidelines for screening.

Colorectal cancer (CRC) is the second leading cause of cancer death in the US with about 150,000 new cases and 50,000 deaths per year.  This module will help you identify the important reasons for colorectal cancer screening for early detection of this disease.
