A breast cancer diagnosis can be complex. There are varying types of the disease.

Breast cancer that is not supported by the hormones estrogen and progesterone nor by the presence of too many HER-2 receptors is called triple negative. It's more rare and does not respond to typical breast cancer medicines.

According to dedicated breast surgeon Dr. Jennifer Joh of The Hoffberger Breast Center at Mercy Medical Center, there is tremendous research happening right now.

"Triple negative breast cancer is a very hot topic because we don't really have great ways of treating the breast cancer, and it does tend to be more aggressive and it does tend to lead to reduced survival rates," Dr. Joh said.

Triple negative accounts for just 10 to 20 percent of breast cancer cases and is more common in young women, African-Americans, Hispanics and those with the BRCA1 gene mutation.
