improve the survival rate for patients with breast cancer, but are still rather the disease than white women to die black women. To understand why, announced the National Institutes of Health (NIH) Wednesday it would launch the largest ever study of the genetics of breast cancer among black women. National Cancer Institute (NCI) Division of the fight against cancer and Population Sciences (DCCPS) administers the grant of 12,000,000 $, the study is funded.
"This effort is to ensure that all Americans, regardless of their origin, the same benefits of the promising advances in medicine to achieve precision," said Dr. Douglas Lowy R., deputy director of the National Cancer Institute part of the NIH, said he in a press release. "I am confident about where this new research may lead us, not only in the treatment of certain profiles of US women breast cancer in Africa, but also the origin of the differences get cancer."
The data show that black women are more often diagnosed than whites with aggressive subtypes of breast cancer. For example, breast cancer rates triple negative, one of these subtypes, is twice as high among black women compared to white women.
Although studies suggest that genetic, environmental and social, such as access to health care can play an important role, the exact reason why the mortality remains unknown for black women with breast cancer.

For the study, researchers compared the genomes of 20,000 black women with breast cancer with 20,000 black women without the disease. The researchers compared the genomes with those of white women with breast cancer as well. Then they are heritable variations risk of breast cancer among black women compared to white women joined look, and to determine the expression of genes in breast cancer tumor samples, examine how they develop genetically tumors.
Robert Croyle, Ph.D., director of "A better understanding of genetic contributions to differences in breast cancer diagnoses and the results in African-Americans can to better treatments and better methods for cancer prevention, lead" the DCCPS he said in the press release.
In October 2015, the American Cancer Society published the results suggest that the incidence of breast cancer in black women had the white woman who reached a disturbing realization due to the higher risk of death already by the disease.
The study found that from January 2014 more than 3.1 million women in the US had a history of breast cancer, but thanks to advances in medicine, 36 have the disease mortality declined percent since 1989. Historically, women have a black lower incidence than white, but in 2012 women, the rate of disease of death by 42 percent higher than in black women than women were white. The authors of the study that it expects to continue the trend.
