Lump and "Indented circles" on Penis. Is this something to worry about?

Don't know what these are or if I should be worried about these (cancer?)

Hey Alex.  I don't see many penises but I think that is the way you were made. I have to say I have never seen the foreskin attached to the front of the head.  I thought the foreskin is on the back of the head.  This makes you unique.  But I would go to a doctor anyway to make sure and tell him your concerns  Ken
