First confirmed common genetic risk factors for breast cancer

...from chance or exposure to an environmental toxin, such as excessive UV sunlight. However, BRCA-1, BRCA-2 and the other previously identified breast cancer susceptibility genes are mutated in a relatively small percentage of women. "Risk mutations within these genes are so rare that only a very small n...

New designer lipid-like peptide with lipid nanostructures for drug delivery systems
