A new study has found that a genetic variant common in some Latina women significantly lowers the risk of breast cancer.

The international study, led by researchers at the University of California, San Francisco, found that women with one copy of the variant were 40 percent less likely to have breast cancer, and women with two copies (only about 1 percent of Latinas) were 80 percent less likely to have the disease.

Dr. Laura Fejerman, one of the authors of the study, joins Take Two to explain why Latinas have lower rates of breast cancer and possible implications for the development of future treatments for the disease.
