What is skin cancer?
Skin cancer is the most commonly diagnosed cancer and, in most cases, it is not life-threatening nor does it spread to other parts of the body. The exception is melanoma, the rarest and most aggressive form of skin cancer.
According to the American Cancer Society, more than 5 million nonmelanoma skin cancers (basal and squamous cell cancers) were diagnosed in 2012. In 2018, melanoma will be diagnosed in approximately 91,270 people.
