Hello and welcome to the forum. Thank you for your question but are sorry you had to ask it. It is the recommendation that you have a doctor look at this patch. There is a high likelihood that it is nothing to worry about but in the off chance that it is something, you would want to treat that. You mention penile cancer which is a possibility although low. Do you have any other symptoms? I would guess that this is something called penile melanosis. This is a harmless condition. Basically melanin (coloring of skin) accumulates in deposits that then look like an area of darker skin. https://www.healthline.com/health/mens-health/penile-discoloration#cancer Please ask your parents to set up a doctors appointment to confirm and have this looked at and let us know what they say.
Thank you for answering, I have made an appointment with the doctor. But before that actually I did forget to leave out something, this is all forming around the line that you have in your penis shaft would that change anything?
Hello, I wanted to check in and see if you've seen your doctor as of yet?
Can these symptoms mean something else like, an infection, or some other type of cancer?
