Either should be checked by your doctor so make an appointment as soon as practicable.

To answer the first person’s comment. No it doesn’t itch, it hasn’t gotten bigger, it’s flat. I went to the beach a few weeks ago but I used sunblock. Idk if it’s from that. It just looks ugly and I’ve never had that before so that’s why I’m concerned

If you are ''worried'' about it then go and see your doctor
and if he/she is concerned about it you will be sent for a biopsy.
We can't tell you .. from a photo.
Does it itch ?
Is it raised or flat ?
Is that how big it's got in just a couple of days ?
It probably is nothing to worry about
.. but if it is cancer the earlier you treat it the better.
