It looks like a basal cell to me but the only way to be sure is to biopsy it.
It definitely doesn’t look like a melanoma though.
If they scrape it out it cost around $300 and has a 5% chance of coming back.
If they cut the skin out it has only a 1% chance of coming back but that’s going
to cost around a thousand.
Also scraping a larger area like that is going to take 2 to3 months to heal
compared to a week with cutting it out.
If it’s gotten that large since last summer it’s not something
you want to wait too long to take care of.
