From today's TimesOnline.com:

Clinics could soon be screening embryos for genes that carry a predisposition to breast cancer and other tumours.

The Human Fertilisation and Embryology Authority announced yesterday that it is to consult the public about letting couples choose embryos free from genetic defects. The defects raise the risk of cancer but do not always trigger it....

Angela McNab, the authority’s chief executive, said... "What we are asking people is whether it is appropriate to use embryo screening technology to stop children being born with faulty genes when there is a chance they may never go on to suffer the cancer."

Who decides what is a "defect"?
