摘要

WOMEN can now buy a test telling them if they carry variants of the BRCA1 and BRCA2 genes that raise their risk of breast cancer That sounds like a welcome advance in medical technology. But the particular variants identified are very rare in the general population. If women buying the test don't understand that, there is a risk they could be lulled into a false sense of security if they test negative.
