A new study out of the University of Michigan's Comprehensive Cancer Center has found that African ancestry may be linked to triple-negative breast cancer, HealthNewsDigest.com
Triple-negative breast cancer is a more aggressive form of the disease and has fewer treatment options compared to other forms. Researchers found that among women with breast cancer, 82 percent of African women had the triple-negative form, 26 percent of African-American women had it and 16 percent of white women had it.
Triple-negative breast cancer is negative for three specific markers that are used by doctors to help determine treatment. With the three markers not being present, doctors are then unable to offer the same course of treatment that would be applied for other forms of the disease.
"The most significant recent advances in breast cancer treatment have involved targeting these three receptors. But these treatments do not help women with triple-negative breast cancer," Dr Lisa A Newman, author of the study, told the news source.
Researchers noted that previous studies have linked race or ethnic backgrounds to hereditary disease, and that screenings may help provide more options if the disease is caught early enough.
The American Cancer Society estimates that over 190,000 women will be diagnosed with breast cancer this year.
