Skin cancer is one of the most common types of cancer globally, with increasing incidence and prevalence rates. According to the World Health Organization (WHO), melanoma is the 17th most common cancer globally, with an estimated 331,722 new cases diagnosed in 2022, while non-melanoma skin cancer affects an estimated 1,234,533 people worldwide. The mortality rates are significant, with approximately 58,667 people dying from melanoma and 69,416 from non-melanoma skin cancer in 2022. Given the alarming statistics, it's essential to understand the causes, symptoms, and prevention strategies for skin cancer.
