Cutaneous SCC Trends Across Sex and Age

Researchers examine how patterns of common skin cancers vary across populations and body sites over time.

1

The study analyzed 109,787 cases of cutaneous squamous cell carcinoma (cSCC) and carcinoma in situ from Denmark between 2005 and 2023.
2

Incidence rates for cSCC reached 131.6 per 100,000 person-years in males and 77.7 in females, with annual increases of 2.6% and 3.1%, respectively.
3

Carcinoma in situ showed a significant rise, particularly after 2018, with incidence rates of 89.4 in males and 78.6 in females.
4

Keratoacanthoma incidence declined over the study period, with rates around 28 per 100,000 person-years for both sexes.
5

The study highlighted age-specific trends, showing higher incidence rates in females aged 40 to 59 years for all keratinocyte neoplasms.
