Skin cancers are caused by exposure to which of the following lights?

Skin cancers are primarily caused by exposure to ultraviolet (UV) light. This type of radiation is emitted by the sun and artificial sources such as tanning beds. UV light has sufficient energy to damage the DNA in skin cells, which can lead to mutations and the development of skin cancer over time.

While other types of light, like blue light and infrared, can have effects on the skin, they are not directly linked to skin cancer in the same way that ultraviolet light is. The violet ray, commonly associated with high-frequency electrical currents used in some beauty treatments, also does not have the same carcinogenic potential as ultraviolet light. Therefore, ultraviolet light is recognized as the primary cause of skin cancers such as melanoma, basal cell carcinoma, and squamous cell carcinoma, emphasizing the importance of sun protection measures to reduce UV exposure.
