Serious health issue, please help me find best doctor for multiple skin cancers?

Surgeon: General plastic or mohs surgeon depending on the type of cancer and location.

Dermatologist +: You should have a dermatologist that is able to track and screen you and decide which are indicated for simple excision vs mohs micrographic surgery vs other modalities. Not every skin cancer requires surgery. If your tumor burden is gret, there are other treatments that can be used and may involve topical or oral therapies. Most importantly, make sure you keep your follow up appointments!
