How to Perform a Self Skin Check for Cancer
A self skin check is about knowing your "baseline" so you can spot changes. You'll need 10 minutes, a full-length mirror, a hand mirror, and a bright room.

1. The Red Flags (ABCDE)
Check every mole or spot for these signs:
A - Asymmetry: One half doesn't match the other.
B - Border: Edges are ragged, notched, or blurred.
C - Color: Shades of tan, brown, black, or even red/blue.
D - Diameter: Larger than 6mm (a pencil eraser).
E - Evolving: Changing in size, shape, color, or starting to itch/bleed.
The "Ugly Duckling": Any spot that looks completely different from all your other moles.
2. The 7-Step Body Scan
Go in this order so you don't miss anything:
Face & Ears: Check your nose, lips, and mouth. Use the hand mirror for the back of your ears.
Scalp: Use a comb or blow dryer to part your hair in sections to see the skin.
Hands & Arms: Check palms, backs of hands, between fingers, and under fingernails. Check forearms and upper arms.
Torso: Check your chest and belly. Women should check underneath breasts.
The Back: Facing away from the big mirror, use the hand mirror to check your neck, shoulders, upper back, and lower back.
Glutes & Legs: Check your buttocks and the backs of your legs.
Feet: Sit down. Check the tops, soles, heels, between toes, and under toenails.

3. What to Do Next
If you find a suspicious spot:
Photograph it: Place a coin or ruler next to it for scale.
Monitor it: Check again in one month to see if it has changed.
