At least once during adulthood, it is a good idea to have an overall skin exam. This enables a dermatologist to gauge your risk factor and see if there are any existing moles or melanoma to be concerned with. This also gives you a starting point so you can then notice if there are any changes in your skin or moles. Those who have a family history or have experienced prior skin cancer should have this type of examination annually. Of course, if you have had several issues with melanoma or skin cancers this should be done more often. It is recommended to perform monthly self-examinations and schedule annual visits to your dermatologist for full body skin exams.
