2 days ago I found a red, shiney lump around the size of a smiley on the skin of the shaft of my penis. I thought if might be an ingrowing hair or something as there was one growing on the lump so I plucked it out, pretty darned painful. It hasn't gone away tho and I can't tell if it's getting smaller or bigger. What shall I do?
Penile cancer question
Most likely just a zit.
Penile cancer is extremely rare. You have a much better chance of getting struck by lightning than getting penile cancer. If it doesn't go away in a week or two, you may want to have it checked by a doctor just to be safe. Peace of mind is a good thing.
