(Ivanhoe Newswire) -- A breast cancer patient's genetic makeup could influence the way she reacts to treatment options. This is the conclusion of a new study conducted by researchers at The University of Texas M.D. Anderson Cancer Center.

Researchers discovered women whose cells harbor harmful mutations in the BRCA genes are likely to view preventive mastectomy as the best way to reduce their risk and fears of developing breast cancer, despite other, less drastic treatment options.

This research could help physicians and other clinicians as they discuss test results with women who undergo BRCA gene testing.

"Health care providers and genetic counselors must take this into account when assessing a woman's needs at the time of genetic testing and results disclosure," study authors wrote.
