I have a personal history of skin cancer as well as suffering from anxiety. To help me manage my derm has been seeing me every three months but has suggested that we do every 4 or 6 months instead (a bit of context I have had two basal cell and one squamous cell cancers - all found in a 3 month period just over 2 years ago). How have people handled moving to longer periods between checks and what has prompted people to go back to the doc sooner if you felt it was needed?
