question: My 17 year old brother says he has a lump on his penis and is very afraid its malignant however from what he is describing it seems like lipoma. He says its about the size of a corn piece and has some veins on the side showing. He said it was painless for a while but that lately he is feeling a pinching pain every now and then and that for some reason the area between his testicles and anus seems to hurt when he sits at a certain position. He is 5' 8" and a bit over weight (I'm guessing 110 kg)
