What is Skin Cancer?

Skin cancer is the uncontrolled growth of abnormal cells in the skin. These cells can damage surrounding tissue and, in some cases, spread to other parts of the body. Ultraviolet (UV) radiation from sunlight is responsible for around 95% of skin cancers. Early detection and timely treatment are strongly linked to better outcomes, while prevention remains the most effective approach.

The three main types of skin cancer correspond to the three most common cell types found in the outer layer of the skin, known as the epidermis:

• Basal cell carcinoma (BCC) is the most common type, accounting for approximately two-thirds of all skin cancers.
• Squamous cell carcinoma (SCC) represents around one-third of skin cancers and has a higher risk of spreading if left untreated.
• Melanoma is less common, making up about 1% of skin cancers, but it is the most dangerous due to its potential to spread rapidly.
