![]() If breast cancer develops, the vaccine is designed to instruct the immune system to attack the tumor and keep it from growing entirely. It is, however, present in most triple-negative breast cancer patients. It’s known as triple negative because it lacks three molecules called receptors. "The difference is not big, so the immune system has a harder time recognizing a cancer cell and distinguishing it from a healthy cell."Īccording to the Cleveland Clinic, the vaccine works by targeting a lactation protein called α-lactalbumin, which is no longer found after lactation in normal, aging tissues. Triple negative breast cancer is a relatively uncommon form of breast cancer that is usually more aggressive and harder to treat than other types of breast cancer. Triple-negative breast cancer (TNBC) is breast cancer that tests negative for all three receptors (oestrogen, progesterone, and HER2). "All of the cells that become cancerous in your body came from normal, healthy cells," Kumar said. If a virus shows up in the body, the immune system teaches itself how to destroy it, knowing, easily, which cells are bad. Triple-negative breast cancers tend to grow and spread more quickly than other types of breast cancer. It's teaching your body to destroy the cells that can grow a tumor," Kumar said. If the cancer cells test negative for both estrogen (ER) and progesterone (PR) hormone receptors as well as human epidermal growth factor receptor 2 (HER2), the diagnosis is referred to as triple negative breast cancer. ![]() "Is it, in essence, teaching your body not to grow a tumor?" CBS13 reporter Ashley Sharp asked.
