Sun exposure can cause cancer
Ultraviolet radiation (UV) is important for our health: it plays an essential role in the production of vitamin D, essential for calcium absorption and bone growth.
However, excessive exposure to UV radiation (either from the sun or from artificial sources such as sun beds) is associated with sunburn, accelerated skin aging and different types of skin cancer.
Between 50 and 90% of skin cancers are caused by excessive UV exposure. According to the International agency for Research on Cancer (IARC), approximately 200,000 cases of melanoma and 46,000 melanoma-associated deaths are reported worldwide every year. In addition, 2.8 million cases of squamous cell carcinoma and 10 million cases of basal cell carcinoma were considered related to excessive UV radiation.
