Colorectal Cancer Journals

Colorectal cancer may be a cancer that starts within the colon or the rectum. These cancers also can be named carcinoma or rectal cancer, counting on where they begin . Colon cancer and rectal cancer are often grouped together because they need many features in common. Cancer starts when cells within the body start to grow out of control. Cells in nearly any a part of the body can become cancer, and may spread to other areas of the body. Most colorectal cancers start as a growth on the inner lining of the colon or rectum. These growths are called polyps. Some sorts of polyps can become cancer over time (usually many years), but not all polyps become cancer. The chance of a polyp becoming cancer depends on the sort of polyp it's . If cancer forms during a polyp, it can grow into the wall of the colon or rectum over time. The wall of the colon and rectum is formed from many layers. Colorectal cancer starts within the innermost layer (the mucosa) and may grow outward through some or all of the opposite layers. When cancer cells are within the wall, they will then grow into blood vessels or lymph.
