Embryo test for breast cancer feasible
PARIS: A lab test to screen embryos for inherited risk of breast or ovarian cancer is "feasible" but controversy surrounding this method is unlikely to be stilled, a fertility conference heard on Monday. European researchers carried out the biggest-ever probe of a procedure to vet invitro embryos for gene mutations linked to these notorious cancers. Their work, presented at a conference in Istanbul, declared the test is a reliable indicator of whether the embryo carries the dangerous BRCA1 and BRCA2 gene variants . Even so, these genes are by no means a guarantee that cancer will occur, which means a fierce debate over the technique will continue, the researchers said.
