I am an uncircumcised 18 year old male. I am a virgin and have never had any sexual contact. I have "Lip" like lesions on the sides of my meatus that I had checked out 2 years ago by a skin doctor. He said not to worry about it and that it was very normal, in other words, nothing serious, and nothing to worry about. These lesions are about 8millimeters in length, they have gotten a little bigger, but that is probably because I have also grown and because Im in puberty. I asked if it was cancer and he told me to stop worrying.
3 weeks ago I noticed a small bump within the "lip" like lesion on the left side of my penis. It was a bit darker in color when compared to the rest of my penis. It is only visible when squeezing the head of my penis, and it looks like a small ball. I thought nothing and then moved on. But yesterday, I was examining it, and I happened to look inside of my urethra. I pulled both sides of the urethra and found that deep into my urethra, again on the left side of the canal, was a dark blue greyish spot on my skin. its very red inside the urethra, but this greyish stuff looks almost like fungus, the color is near black, and now I am very scared that It could be cancer. I tried to touch it with a cotton swab with alcohol, hoping it would come off, but it wouldn't, so it now looks like its in the skin of the urethra or something. I am really really scared this is cancer. Is there any possibility this could be a vein? it sure doesn't look like one though, its all fuzzy looking and kind of black. if it is a tumor, how would I know? there is no pain at the tip of my penis, no discharge, or anything really. what could it be? any feedback or help would be appreciated. thank you.
