If a suspicious lesion is found, they can be treated in a variety of ways. First, the doctor could chose to simply monitor the lesion over time. Often, a biopsy is taken during your appointment, and sent to an outside pathology lab for evaluation. Lab results are generally received in 7-14 days, at which time you will be contacted with the results. If a skin cancer is detected, the physician will have your return for treatment or removal of the lesion.
