I am very much concerned about this issue. I have got a bump on the bottom part of my penis. It is not so big in size also. It is seen right on the bottom of the penis and at the middle. It is under the skin and is not hurting at all. I don’t know how it occurred. Could it be some sort of lymphocele or cancer? Or anything else? Anyway, I know that it is not normal and wish to know what it is.
