I think I have a little growth around the opening of my anus. I'm not sure how to address the situation. What should I do?
It is very important that any growths that you have found around the anus be seen by a colon and rectal surgeon. While they are often benign, a few will be cancer and if discovered early are very curative.

You should set up an appointment with a colon and rectal surgeon so that the growth can be examined and diagnosed.
