Baby to be born free of breast cancer after embryo screening
A woman has conceived Britain’s first baby guaranteed to be free from hereditary breast cancer.

Doctors screened out from the woman’s embryos an inherited gene that would have left the baby with a greater than 50% chance of developing the cancer.

The woman decided to have her embryos screened because her husband had tested positive for the gene and his sister, mother, grandmother and cousin have all had the cancer.

The couple produced 11 embryos, of which five were found to be free from the gene. Two of these were implanted in the woman’s womb and she is now 14 weeks pregnant.

By screening out embryos carrying the gene, called BRCA-1, the couple, from London, will eliminate the hereditary disease from their lineage.
