I have new moles growing where i had two blistering sun burns from the tanning bed. could they be cancerous?

I would have: These evaluated by a dermatologist. Can't know if they are malignant without a biopsy. Please don't use a tanning bed.

Maybe: It is hard to answer your question without an examination. Tanning beds can lead to skin cancer. It is concerning that new moles have developed. It is also concerning when moles change - change in size, color, become irregularly shaped, itch, bleed. Most moles are relatively easy to remove and test. Please see your primary doctor or a surgeon to see if this needs to be removed and tested.
