How do you get anal cancer?

Answer 1

One of the main causes for colorectal cancer is diet. A diet high in animal protein, fat and sugar can lead to such cancers. To maintain good health of the digestive system a person should incorporate more fiber into their diet.

Answer 2

You can get anal gonorrhea from anal sex with someone who's infected. There's also some evidence that it can spread without anal sex from the vaginal to the rectum.
