Is anything wrong if I have a rash, bumps, or swelling in my penis?

Rash, bumps, or swelling (other than swelling during erection) are never normal on your penis. Several conditions, including penile cancer, could cause these symptoms. Other possible causes may be more or less serious than penile cancer. Do not take chances with your health. If you notice any of these symptoms on your penis, see your doctor as soon as possible so that a correct diagnosis can be made.
