I am presently visiting Chiang Mai and went to a young male dermatologist at Chiang Mai Ram Hospital today. I have two problem "spots" which will not heal and I know something has to be done but this guy immediately said I had to have biopsies and probably, plastic surgery. I did not like his manner and he was making an appointment immediately for me for the biopsied without discussing price. Any recommendations for a good English speaking dermatologist experienced with carcinomas?
