UVA Not The Cause of Melanoma Skin Cancer
Scientists from The University of Texas MD Anderson Cancer Center have just released a new study about the correlation of UVA light and melanoma skin cancer. Test results show that UVA exposure does not actually cause this deadly form of skin cancer. Since the ealry nineties when the original research was completed about the association of melanoma and UVA, it has been believed that UVA indeed does cause deadly melanoma skin cancer. This new study’s lead author David Mitchell, Ph.D., professor in M. D. Anderson’s Department of Carcinogenesis located at its Science Park — Research Division in Smithville, Texas, worked with a team of experts to replicate the original testing that was done in the nineties as well as conduct new tests. Their results negate the original findings and establish clearly that there is not connection between melanoma skin cancer and UVA light exposure. “Our data refute the only direct evidence that UVA causes melanoma, which is not to say that UVA is harmless,” explained Dr. Mitchel. “UVA is just not as dangerous as we thought because it doesn’t cause melanoma.” The researchers clearly stated that UVA is still harmful and can lead to more benign forms of skin cancer such as squamous cell carcinoma. Over exposure can also lead to premature aging and immune system suppression.
