Immunotherapy offers promising treatment for ER-positive breast cancer. Keytruda is one such option. Here's a guide to help you understand it better and maximize your treatment’s effectiveness.
Immunotherapy is a type of treatment that uses the body's own immune system to fight cancer. Unlike traditional methods such as chemotherapy or radiation, immunotherapy specifically targets cancer cells, sparing very healthy cells.
Immunotherapy works by either stimulating the immune system to work harder or smarter in attacking cancer cells or by providing the immune system with additional components, such as man-made immune system proteins.
ER-positive breast cancer is a type of breast cancer that expresses estrogen receptors. These types of cancer cells rely on estrogen to grow and multiply. This characteristic makes them respond positively to hormonal therapies that block or lower estrogen levels.
Keytruda (pembrolizumab) is an immune checkpoint inhibitor. It works by blocking the PD-1/PD-L1 pathway, which cancer cells often use to hide from the immune system, thereby allowing the immune system to recognize and destroy these cells.
Keytruda is typically given through an intravenous (IV) infusion. The treatment schedule can vary but is often administered every three to six weeks.
Immunotherapy, particularly with Keytruda, offers hope for many battling ER-positive breast cancer. By understanding your treatment and making necessary lifestyle adjustments, you can take an active role in managing your health. Consult your healthcare team regularly and stay informed on the latest developments to ensure you receive the top possible care.
