Safe tanning is a myth, according to U.S. and British researchers. They say that tanning causes DNA damage that could lead to cancer. The worst cancer from tanning, malignant melanoma, is caused by too much ultraviolet radiation, but having no sun is just as bad. Ultraviolet radiation causes the body to produce Vitamin D, though it takes less exposure to do this than it takes to tan.
People can expose themselves to ultraviolet radiation in moderation if they want to be healthy, but there should be laws preventing too much exposure. If not, people could develop certain cancers that could kill. Malignant melanoma, the worst skin cancer from tanning, claims 60,000 people a year. This has to be stopped or thousands of people will suffer the consequences.
