Hello. For about 5 years i have had some brown scaly skin on the right side of my penis. Over the past few years this skin seems to have spread and is now on the head and left of my penis. The skin on the right also seems to be a lot thicker than normal. I am 24 years old and uncircumsized. I went to the doctor about a week ago but i was so nervous that my penis seems to try to be hiding haha. It seriously just shriveled up and even i could not see the discoloured skin, it seemed normal. Should i go back to the doctor for a second visit? I am worried that it is the beginnings of penile cancer. The doctor just said "dont worry" and sent me on my way, unfortuantly after the research ive been doing i am worried sick.
