One of my moles recently started to bleed. is that a sign of skin cancer? i'm a red head with very pale skin.

See your doctor: A bleeding mole is a warning sign. Please see your doctor to ascertain if the lesion needs to be removed for examination by a pathologist.

Could be: One of the classic signs of cancer is a change in mole or freckle. Certainly, you should have this checked out. You need to be ever vigilant with your complexion. Use an spf 15-30 skin creme, wear a hat, and avoid long exposures to sun. Good luck.

Possibly: This requires evaluation by a specialist. A biopsy might be required.

Could be: You should alert your dermatologist to any changes in your existing moles. It is time to see your dermatologist.
