Does a family doctor know how to check for skin cancer?

He should: All family physicians know that an unusual pigmented lesion, an ulcer of skin that doesn't heal or an increasing skin nodular lesion is atypical and should be biopsies or at least examined by a dermatologist. He should also know that as one gets older and into the 60's that skin deposits don't shed but build up and become pigmented as senile keratosis, so that one can usually trust the GP.
