A member asked:

I have a scab on my arm that won't heal it's been there for over 6 months what could be wrong?

A doctor has provided 1 answer

May need biopsy: Anything that does not heal after one month requires a check by a dermatologist to make sure that it is not skin cancer. If suspected, he/she can do a biopsy for further examination and confirmation of the exact diagnosis.
