The prices stated above sound hugely expensive. I have had many BCCs biopsied then removed and never paid more than 6000 baht. Dr Vachiraporn at Chiang Mai Ram hospital is highly skilled in dealing with skin cancers (tarined in the US) and her fees are very reasonable. Due to large number of keratosis and BCCs I have had treated over the last 30 years or so I currently have 6 monthly checkups with Dr Vachiraporn.
