There is a small lump in the left side of my penis, on the shaft near the head. It's under the skin and can't be seen, and I can only feel it when I have an erection. There is also some swelling in the left side of my penis.
There's no pain. I also have swollen lymph nodes in the groin and neck. Could these have something to do with each other? I have seen two doctors but they only said "let's wait and see...".
So what is this? A cancer? Lymphoma spread to my penis? I'm shocked.
