Skin Cancer
24 February 2025
Introduction
Skin cancer includes non-melanoma and melanoma. It accounted for 3.1% of all new cancer cases in 2022.
Incidence
In 2022, there were 1 097 new cases of skin cancer, with 1 006 cases of non-melanoma and 91 cases of melanoma. The crude incidence rates were 13.7 and 1.2 for non-melanoma and melanoma per 100 000 population respectively. The age-standardised incidence rates* were 6.0 for non-melanoma and 0.6 for melanoma per 100 000 standard population.
Trend of incidence
The age-standardised incidence rate of overall skin cancer (both non-melanoma and melanoma) and non-melanoma had no significant trend over the past 40 years and over the past 10 years.
The age-standardised incidence rate of melanoma had no significant trend over the past 40 years, while an upward trend was observed over the past 10 years (average annual percentage change (AAPC)# between 2013 and 2022: 1.0%).

Mortality
In 2023, a total of 75 people died from skin cancer which accounted for 0.5% of all cancer deaths. 23 deaths were due to non-melanoma and 52 deaths were due to melanoma. The crude death rates were 0.3 and 0.7 for non-melanoma and melanoma per 100 000 population respectively. The age-standardised death rates* for non-melanoma and melanoma were 0.1 and 0.3 per 100 000 standard population respectively.
Trend of mortality
The age-standardised death rate of overall skin cancer (both non-melanoma and melanoma) had no significant trend over the past 43 years and over the past 10 years.
The age-standardised death rate of non-melanoma had a downward trend over the past 43 years (average annual percentage change (AAPC)# between 1981 and 2023: -1.5%) and over the past 10 years (AAPC between 2014 and 2023: -1.5%).
The age-standardised death rate of melanoma had an upward trend over the past 43 years (AAPC between 1981 and 2023: 2.1%), while no significant trend was observed over the past 10 years.
