The overall burden of disease for melanoma is increasing, according to a study comparing incidence in 2016 and 2009.

Investigators looked at the number of invasive melanomas reported for both years. They then calculated the lifetime risk of developing a melanoma, and determined the annual percentage growth rate over 7 years. Among the results:

• More than 76,000 Americans were estimated to be diagnosed with invasive melanoma in 2016.
• Raw incidence rates per 100,000 population rose to 23.6 from 22.2.
• The current lifetime risk of an American developing invasive melanoma is 1 in 54, vs 1 in 58 in 2009.
• In situ melanoma incidence has risen to 1 in 58 from 1 in 78.
• The lifetime risk for being diagnosed with invasive or in situ melanoma is now 1 in 28.
• It is estimated that more than 10,000 Americans died from melanoma in 2016, vs ~8,600 in 2009.
