The rectum is the last portion of the bowel, and an amazing organ for preserving human dignity. It can tell the difference between solid, liquid, and gas, releasing each at the proper time. Common problems in this area include itching and hemorrhoids, but rarely cancer may develop in the anal canal. There are actually four types of tissue in the anal canal, which can give rise to different cancers.If someone develops rectal cancer, it is critical to get prompt diagnosis and proper treatment. Getting the best treatment can make the difference between having an "sphincter sparing" operation, where the anus is preserved, or having to wear a colostomy bag to drain stool from the abdomen. Moreover, proper treatment can make the difference between life and death.
