I found a dark brown mole on the side of my penis that i did not have before. it is pretty big and has uneven borders. can you get skin cancer ther?

Yes you can: See a dermatologist asap. Penile cancers are notoriously bad. The earlier the intervention, the better the outcome. Good luck from nyc.

Yes: Yes you can, see your doc right away bro. Hopefully is nothing serious but needs to be checked. Regards.

New moles: Any new mole, particularly one that is dark and has irregular borders needs to be shown to a dermatologist as soon as possible to rule out melanoma.
