No one in the world has more experience than Australian dermatologists. The melanoma clinic at RPA in Sydney has many French Spanish Irish doctors who've come to learn. A skin check there is about $300; free if you're a pensioner. So that's 7,500 baht, plus your airfare is, say, 20,000 baht. For Dr. Anna to cut out 2 non- malignant naevi at BPH was 23,000 baht. So I think it's worth a trip home to Oz. Of course you have to make an appointment weeks and weeks ahead.
