Many studies have indicated that early skin cancer detection and treatment leads to better outcomes. To spot skin cancer early, you must be very familiar with your skin. You gain this familiarity by examining your skin monthly. Your monthly skin cancer self-exams involve looking at every inch of the skin on your body, including your scalp. It's convenient to perform these exams before or after a shower. You can observe much of your skin easily but will need to use a handheld mirror to see your back, the back of your neck, and your genital area (yes, you can get skin cancer there, too). It may be easiest to start at one end of your body and gradually work your way up or down.
