Your family doctor is well trained to assess you for skin cancer. If you have a mole, freckle or other skin lesion that is new, changing, large, asymmetric, has irregular borders, is variably colored, is bleeding, irritating or is otherwise bothering you it is wise to have it checked out sooner rather than later. If you need to see a subspecialist, your family doctor may refer you to a dermatologist (a doctor who specializes in skin diseases).
