Victoria has experienced an increase in non-melanoma skin cancer treatments, with over 170,000 procedures recorded last year. This represents a 12.3% rise from an estimated 151,355 treatments in 2022, according to Medicare data analyzed by Cancer Council Victoria. This increase outpaces the state's population growth of approximately 5% over the same period.
Types of Non-Melanoma Skin Cancer
Non-melanoma skin cancers, while less deadly than melanoma, are significantly more frequent. The two primary types are basal cell carcinoma and squamous cell carcinoma. Basal cell carcinoma constitutes about 70% of non-melanoma cases in Australia, originating in the lower epidermis and commonly found on areas like the shoulders and back. Squamous cell carcinoma, less common, starts in the upper epidermis and often appears on forearms and lower legs.
Regional Risk Factors
Recent findings from the Victorian Cancer Registry indicate that regional Victorians are 51% more likely to be diagnosed with melanoma and 35% more likely to die from it compared to residents of Greater Melbourne and Geelong.
Louise Bibby, from regional Victoria, had her first basal cell carcinoma removed at 22, despite practicing sun safety as a child. She has since undergone numerous surgeries on her face, scalp, and chest, underscoring the necessity of early detection and regular skin checks.
Prevention and Awareness
Emma Glassenbury, head of SunSmart at Cancer Council Victoria, emphasized the seriousness of non-melanoma skin cancers, which can be fatal if not managed. She stated that 95% of melanomas and 99% of non-melanoma skin cancers are largely preventable through appropriate sun protection measures.
Key risk factors include fair skin, a history of severe sunburn (especially during youth), a family history of skin cancer, and a high number of moles. Individuals are advised to become familiar with their skin, monitor for any changes, and consult a GP for concerns, potentially establishing a skin plan if at high risk. Essential sun protection includes wearing hats, long-sleeved clothing, sunscreen, sunglasses, and seeking shade, particularly during periods of high UV levels.
