Receptors are how we often successfully target cancer cells and when there are no receptors, those same medications may not work. Our sisters with metastatic triple negative breast cancer have a particularly rough experience since the only medication that is usually effective are the harshest IV chemotherapeutic agents. This can mean some very rough days and lots of long lasting side effects.
Knowing your subtype and what to do to treat it is so very key. This is also why breast cancer isn’t so easy to solve — the different subtypes are often nearly different diseases. And when someone talks about one experience, which is very different from another person’s, it is often because they have different types of breast cancer.
Knowledge is power and we all need more!
