Triple Negative Breast Cancer

Triple-negative breast cancer is a type of invasive carcinoma of the breast that does not have the three most common receptors known to "fuel" breast cancer, estrogen, progesterone, and HER-2. Invasive ductal carcinoma is the most commonly diagnosed breast cancer, accounting for about 8 out of 10 cases of invasive breast cancers.

Triple-negative breast cancers tend to grow and spread more quickly than other types of breast cancer. Because of this, triple-negative breast cancer is more aggressive than other forms of breast cancer.

Triple-negative breast cancer is treated at the Abramson Cancer Center, within the Rena Rowan Breast Cancer Center, and within the Integrated Breast Center at Pennsylvania Hospital.
