I recently had a mole on my back that had increased in size and started itching me all the time. I went to a dermatologist and he surgically removed it and sent it for a biopsy. Luckily it was benign. It is always a good idea if you have any moles that change either in size or color or become irritated to have them checked out by a dermatologist. I have had several removed throughout the years and so far all have been benign.
Keep us informed.
