Breast cancer risk lasts a lifetime for sisters

Once you've had a sister with breast cancer, many women wonder if they are next in line.A new study finds women with this kind of family history have roughly double the risk as women in the general population.

Young women need to be especially vigilant. Those between the age of 20 to 39 were more than six times as likely to develop the disease themselves.

And the risk remained elevated even when their sisters had been diagnosed 20 years in the past.

Experts say these findings mean regular screenings are particularly important for women with breast cancer in their family.
