How are skin changes a warning sign of cancer?

ANSWER

A telltale sign of skin cancer is a growth that starts to look different or a sore that doesn't heal. See a dermatologist for any spot that:

  • Gets bigger or thicker
  • Changes color
  • Has an oddly-shaped border
  • Is bigger than a pencil eraser
  • Crusts or scabs over and doesn't heal
