Cancer Discoveries

News is traveling around on the internet that scientists have discovered the cause of cancer. Studies of skin and lung cancer have shown that mutations in the DNA in those parts of the body are caused by exposure to cigarette smoke and ultraviolet light from the sun and some of those changes make the cells become cancerous. It's likely that other forms of cancer are also caused by genetic mutations.

It will take a lot more research before scientists can discover treatments that can cure cancer, but at least this is a step in the right direction and offers hope that someday a cure will be developed.

In the meantime the study offers convincing evidence of the dangers of smoking and too much sun exposure. Perhaps the study will convince more people to protect themselves from those dangers and, as a result, cut down on the frequency of melanoma and lung cancer.
