Here's a step-by-step guide to performing a self-exam:
Stand in front of a full-length mirror and use a hand-held mirror for hard-to-see areas. Check your face, ears, neck, chest, and belly. Women should lift breasts to check the skin underneath. Inspect underarm areas, both sides of your arms, the tops and palms of your hands, and between fingers and nails. Sit down to examine the front and back of your thighs, shins, tops of feet, and between toes and nails. Use the hand-held mirror to check the back of your neck, scalp, back, and buttocks.
