I would get it checked, the sooner the better! I had a melanoma on my shoulder that my
primary care doc found. Very similar to yours. Mine was positive stage 1. All I had to do
is get it cut out, and a nice scar on my shoulder. No problem, I’ll trade that any day. Nothing
to delay on get it checked. From USA, Calif.

See a dermatologist right away, skin cancer of any type is no joke. yours looks small and will probably be easy to treat.
