Scientists in California have identified a new gene that indicates a heightened risk of breast cancer in women.
Women with the rare PALB2 gene mutation have a 35 percent chance of getting cancer by the age of 70. By comparison, women with the BRCA1 gene mutation have about 50 to 70 percent chance of getting breast cancer by the same age.
The study is out of the City of Hope Cancer Center in Duarte, California.
It appears in this week's New England Journal of Medicine.
