Skin cancer, also called cutaneous cancer, is the abnormal growth of skin cells, most often caused by uncontrolled exposure to ultraviolet (UV) radiation from the sun or tanning devices. It is the most common type of cancer worldwide.
Symptoms vary with type but often include new growths, sores that don’t heal, unusual moles, or changes in the shape, color, or size of existing moles. Having fair skin, excessive sun exposure, frequent sunburns, a weakened immune system, a family history of skin cancer, and use of tanning beds can increase the risk.
Treatment depends on the stage and type of the disease and may involve excision, radiation therapy, immunotherapy, targeted therapy, or chemotherapy. Early detection greatly improves survival, making regular skin checks essential.
