The danger signs of a lesion

Most cancer lesions are not associated with bleeding, scab formation or pain. So what are the danger signs?


Contact your dermatologist if a skin lesion:

  • changes colour: from light to dark or white to pale pink
  • changes shape and size
  • develops irregular, swollen ridges
  • peels, heals and peels again
  • forms an ulcer in the centre and doesn’t heal
  • suddenly reappears.

Note: Most cancer lesions are not associated with bleeding, scab formation or pain.
