What causes a mole to turn cancerous?

Is melanoma a death sentence?
Stage 4 melanoma used to be a death sentence. The disease doesn’t respond to radiation or chemotherapy, and patients survived, on average, less than a year. But over the last decade, doctors are successfully using a new approach, one significantly different than the treatment options available for the last 150 years.
Are Raised moles dangerous?
The vast majority of moles are not dangerous. Moles that are more likely to be cancer are those that look different than other existing moles or those that first appear after age 25. If you notice changes in a mole’s color, height, size, or shape, you should have a dermatologist (skin doctor) evaluate it.
When should I be worried about a mole?
