A genetic test may be able to help predict breast cancer before a diagnosis.
A new cancer study finds that biomarkers in the DNA of some women can help find those susceptible to breast cancer years before a diagnosis. The test looks at how environmental factors can lead to the methylation of a single gene called the ATM.
“The scientists from Imperial College London analysed blood samples from 1,380 women of various ages, 640 of whom went on to develop breast cancer.” reports BBC
Women with the highest levels of ATM, are twice as likely to develop breast cancer, than those with low levels. Although this study does not conclusively predict breast cancer, it increases the chances of discovering those that may develop breast cancer, especially if it runs in the family.
