Quizplus · Accepted Answer

Cutaneous carcinomas, which include basal and squamous cell carcinomas, are most commonly caused by regular exposure to ultraviolet (UV) light, usually from the sun. UV radiation damages the DNA in skin cells, leading to mutations that can result in cancer. X-rays and gamma radiation can also cause cancer, but they are not typically associated with cutaneous carcinomas. Mutagenic chemicals can also increase the risk of cancer, but their role in causing cutaneous carcinomas is less clear.
