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.
Understanding Immunotherapy
What is Immunotherapy?
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.
How Does Immunotherapy Work?
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.
Overview of ER-Positive Breast Cancer
What is ER-Positive Breast Cancer?
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.
Characteristics and Diagnosis
Hormone Receptor Test
: Determines if cancer cells have receptors for the hormones estrogen (ER) and progesterone (PR).Treatment Sensitivity
: ER-positive cancers might be more responsive to hormonal treatments, which can sometimes slow or stop cancer growth.
Keytruda: A Game-Changer in Immunotherapy
What is Keytruda?
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.
How is Keytruda Administered?
Keytruda is typically given through an intravenous (IV) infusion. The treatment schedule can vary but is often administered every three to six weeks.
