Key ideas in Skin Deep: Reading the Body's Surface
- Healthy moles stay consistent in height and shape over time
- Stability is a sign of healthy, controlled skin cells

- Recent changes in appearance signal active, uncontrolled growth
- Identify which specific change in a mole's appearance is most concerning
- Understand why change over time is the primary warning sign of skin cancer
- Dangerous moles often develop blurred or ragged edges
- A mole that begins to itch, crust, or bleed is signaling a problem
- Stability vs Change
- Uniform color indicates pigment is being produced evenly
- Distinguish between normal growth and dangerous evolution
- Multiple shades suggest different groups of cells are growing at different rates
- Interpret the meaning of multiple colors within a single mole
- Most people have a 'signature' mole type that looks similar across their body
- A mole that breaks the pattern of your other spots is a high-priority warning
- Rapid changes in size or color are the most urgent warning signs
