Skin cancer is primarily caused by exposure to ultraviolet (UV) radiation, which can induce DNA damage in skin cells. This radiation can be from natural sources, such as sunlight, or artificial sources, including tanning beds. Other chemical agents known as carcinogens can also contribute to skin cancer. These may include substances found in industrial pollution, tobacco smoke, and certain workplace environments, such as polycyclic aromatic hydrocarbons (PAHs) and arsenic.
