South Australia, despite having lower rates than some other Australian states, faces a significant skin cancer burden, with melanoma and non-melanoma skin cancers (NMSC) being common, particularly in older men.

 

The state's Cancer Registry recorded 831 melanoma diagnoses in 2021, and skin cancer is a leading cause of disease, with preventative measures like the SunSmart campaign and UV protection being crucial.

 

Prevalence and Incidence
Melanoma: In 2021, 831 South Australians were diagnosed with melanoma. Data from 2020 showed 864 diagnoses, with men disproportionately represented.
Non-Melanoma Skin Cancers (NMSC): NMSC (also called keratinocyte cancers), like basal and squamous cell carcinomas, are common, though the incidence is lower than the national average and much lower in younger populations than in previous decades.
Lifetime Risk: Two in three Australians are diagnosed with some form of skin cancer before the age of 70, and one in 36 South Australians are at risk of developing melanoma in their lifetime.

 

Risk Factors and Causes
UV Radiation: The sun's ultraviolet (UV) radiation is the primary cause of skin cancer.
Sun Exposure in Youth: Damage from sun exposure in youth is a significant factor, as most damage is done during childhood and adolescence.
Moles: Having a higher number of moles can increase your risk of developing melanoma.
