Photocarcinogenesis refers to the process by which ultraviolet (UV) radiation from the sun induces skin cancer. UV radiation can cause damage to the DNA in skin cells, leading to mutations that can eventually result in the development of cancer. This research area focuses on understanding the molecular mechanisms underlying photocarcinogenesis, as well as identifying potential preventive and therapeutic strategies to reduce the risk of skin cancer caused by UV exposure. Studies in this field often investigate the role of specific genes, signaling pathways, and cellular processes involved in the development of UV-induced skin cancer. Additionally, research in this area may also explore the use of sunscreen, protective clothing, and other strategies to minimize the harmful effects of UV radiation on the skin.
