How common is melanoma?

More and more people are being diagnosed with the skin cancer called melanoma, but we're not sure why.

  • About 60,000 people in the United States are diagnosed with melanoma each year.

The number of people being diagnosed with melanomas is rising faster than the number of people with most other types of cancer.

But it's probably also true that more people are getting melanomas. There are different ideas about why this may be happening. It may be because:

  • People are living longer and getting melanomas when they are older

The good news is that the number of people dying from melanoma is not going up as fast as the number of people being diagnosed. This may be because we're finding melanomas earlier, when there's a good chance that they can be cured.
