Yes, it is standard for a complete dermo exam - that the doc examine ever inch of your body -literally - from between your toes to your scalp for any signs of cancer... of they dont they are being lazy... I've had skin cancer six times and its been caught so that simple surguires were the cure, before it matasized..... if these exams had not been done - mestsized melanoma is one of the toughest cancers to fight... (also, taking pictures of you to compare for future exams is sometimes done too) (I would expect however a paper gown for medesty sake)

so let them check!
