Colon and rectal cancer is cancer that forms in the tissues of the colon (the longest part of the large intestine). Most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids).
This guide is designed to help you make an informed decision about your colon cancer screening options. As with most things, one size doesn't fit all. Think of yourself and your doctor as partners in the decision-making process. Your decision about what screening test or tests are best for you will most likely be based on a number of factors, including your age, medical history, and comfort level.
The anatomy of the human female breast contains various tissues and structures. One of the primary functions of the breast is milk production. Learn about breast ducts, muscles, and blood vessels in this slide show from the Mayo Clinic.
Breast cancer is classified from stage 0 (zero) to stage IV (four). The stages are determined by a sample of breast tissue, as well as examination of tissue from the lymph nodes under your arm. The purpose of staging is to estimate the chances of survival of at least five years after diagnosis. Learn about breast cancer staging with this slide show from the Mayo Clinic.
