We are continuously bombarded with messages about the dangers of too much sun and the increased risk of melanoma, but are these dangers real, or is staying out of the sun causing us more harm than good?
Researchers have identified a type of cancer stem cell that might initiate metastatic cancer, which spreads beyond the original, primary tumor site and to other locations within the body. For the first time, scientists have revealed that the molecular profiles of these cancer stem cells are much different than those located in primary tumors.
Researchers found a new protein produced excessively in malignant melanoma, a discovery that is particularly relevant as skin cancer rates climb dramatically among young women. The protein, IMP-3, is not over-expressed in harmless moles but is increased in the most dangerous types of skin cancer, and in a subset of lesions that can be difficult to predict called thin melanomas.
A gene that is overexpressed in 20 percent of breast cancers increases the number of cancer stem cells, the cells that fuel a tumor's growth and spread, according to a new study from the University of Michigan Comprehensive Cancer Center.
As bombs burst in air this July 4, chances are that sunburn will be the red glare that most folks see -- and feel. But unfortunately, even when there is no burn, the effects of the sun's ultraviolet rays can have deadly consequences. Thanks to new research scientists now know why UVB light is more likely to cause skin cancer than UVA light.
