It’s not uncommon for one person to have dozens of moles. Most of them develop over the course of a lifetime, and the majority of them are nothing to worry about. But because abnormal changes in moles might indicate skin cancer, a dermatologist should check them out. It’s recommended that every adult schedule a skin cancer screening once each year, or perhaps more often if you have a history of skin cancer.
You should have your moles examined and documented. This allows for comparison later on. Moles that grow larger, change in color, or otherwise change dramatically in a short period of time should be examined by a dermatologist promptly. Before you leave your appointment, ask the doctor for tips on performing a skin self-exam at home. Adults should do skin self-checks once per month, although this isn’t a substitute for annual screenings by the doctor.
