What is the most common type of skin cancer?

Basal cell carcinoma is the most common type of skin cancer, accounting for a significant majority of all skin cancer cases. It originates in the basal cells, which are located in the lower part of the epidermis, and is primarily caused by prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. This form of skin cancer is typically slow-growing and often appears as a persistent, non-healing sore, a shiny bump, or a reddish patch of skin.

Due to its prevalence, it is essential for individuals to regularly examine their skin for changes and consult a healthcare professional for any concerning spots, as early detection and treatment can lead to excellent outcomes. While melanoma and squamous cell carcinoma also pose serious risks, they are less common compared to basal cell carcinoma. Atypical nevi, on the other hand, refer to unusual moles that may have the potential to develop into melanoma but are not a type of skin cancer themselves.
