Utah now sits at the top of the national melanoma chart, logging the highest rate of new cases in the country, while the District of Columbia comes in with the lowest. Across the United States there are about 24 new melanoma cases per 100,000 people (age-adjusted). Utah is running at roughly 44 per 100,000, and D.C. at around 11. Those numbers point to a simple takeaway: sunlight alone does not explain where melanoma shows up. Who lives in a state, how people tan, and how aggressively doctors screen all factor into the picture.
As Axios reported, a new state-by-state map based on federal cancer registry data puts Utah and D.C. at opposite ends of the spectrum, with the national age-adjusted incidence sitting near 24 cases per 100,000. The map draws on data compiled by the National Cancer Institute and Centers for Disease Control and Prevention and reflects the most recent federal counts for new invasive melanoma diagnoses.
Demographics Drive State Differences
One big reason states diverge so sharply is simple demographics. Data from the U.S. Census Bureau for North Dakota and the U.S. Census Bureau for Minnesota show that roughly four out of five residents in each state are non-Hispanic White. The American Cancer Society notes that melanoma is far more common in non-Hispanic White people. That combination helps explain why some relatively less sunny northern states can land high on the melanoma list, while more diverse sun-belt states do not always top the charts.
Indoor Tanning Leaves A Mark
Behavior and medical history layer more nuance onto the map. A genomic study led by Northwestern Medicine and the University of California, San Francisco found that indoor tanning is tied to nearly a threefold jump in melanoma risk and leaves distinct mutation patterns across much of the skin, according to Northwestern Medicine. Researchers say that pattern helps explain why tanning bed use can drive melanoma risk even on body parts that rarely see actual sunshine.
Screening And Detection Also Affect Numbers
How hard clinicians look for cancer also changes the math. Memorial Sloan Kettering dermatologist Anthony Rossi told Axios that more aggressive screening means doctors are now catching cancers that might once have gone unnoticed. The Skin Cancer Foundation reports that new invasive melanoma diagnoses climbed by roughly 47% over the past decade, a rise experts link to both shifting exposure patterns and better detection. In other words, some of the jump is more cancer, and some of it is more eyes on the problem.
What To Do
Public health advice remains stubbornly consistent: skip indoor tanning, cover up when you can, use broad-spectrum sunscreen, and keep up with routine skin checks. The American Cancer Society continues to emphasize early detection and sun protection as the best defenses against melanoma.
So Utah’s top ranking might surprise anyone who assumes melanoma is simply about living in a sunny place. The data tell a more complicated story that mixes demographics, behavior and clinical practice. For everyone else, the takeaway is straightforward: prevention and regular skin checks matter, whether you live in the mountains, the desert or a D.C. high-rise.
