Hormone receptor-negative breast cancer cells lack a receptor for either progesterone or estrogen. This means these cells do not grow in response to hormones and hormone therapy is not effective against them. Hormone receptor-negative breast cancer tumors tend to grow faster than hormone receptor-positive ones. Around 25 to 30 percent of breast cancers are hormone receptor negative. They are more common in women who have not gone through menopause.

If you are diagnosed with hormone receptor-negative breast cancer, your doctor will most likely recommend surgery as the first line of treatment. Surgery for breast cancer involves removing either part (lumpectomy) or all of the affected breast or breasts (mastectomy). The stage of breast cancer will determine the type of surgery. If the entire breast is not removed, radiation therapy is used to make sure any remaining cancer cells are destroyed.
Chemotherapy is another common treatment for hormone receptor-negative breast cancer. If your tumor is positive for the HER2 protein, targeted therapies may also be an option. These drugs use a marker on the cancer cells to identify and destroy them.
If you have hormone receptor-negative breast cancer, you may be frustrated that hormone therapy is not an option for you. It’s important to remember that chemotherapy, radiation, and surgery are highly effective treatments for your type of cancer. In fact, some studies have found that chemotherapy may be more effective against hormone receptor-negative tumors than hormone receptor-positive tumors.
