HealthDay News — In recent years there has been an increase in melanoma incidence, with more than 70% of melanomas diagnosed among those aged 55 years and older, according to a research letter published online in JAMA Dermatology.

Dawn M. Holman, MPH, from the US Centers for Disease Control and Prevention in Atlanta, and colleagues calculated incidence rates for melanoma from January 2010 to December 2014 for non-Hispanic whites (NHWs) aged 15 years or older.

The researchers found that 192,979 melanomas were diagnosed among NHW men and 131,976 melanomas were diagnosed among NHW women from January 2010 to December 2014. Most melanomas (more than 70%) were diagnosed in those aged 55 years or older.

The incidence rates varied from 2 to 198.3 per 100,000 among those aged 15 to 24 and >85 years, respectively, for males, and from 4.5 to 60.9 per 100,000 in the same age groups for women. From January 2005 to December 2014, there were statistically significant increases in melanoma incidence among both NHW men and women aged 15 years and older.

For men and women combined and for men only, incidence decreased significantly among those aged 15 to 24, 25 to 34, and 35 to 44 years, and increased significantly for those aged 55 years and older.

“The steady increase in melanoma incidence rates among older adults indicates a need for efforts that promote skin cancer preventive behaviors throughout adulthood,” the authors write.
