What Kind of Medicine Is This?
Simply put, Zanubrutinib is a medicine used to treat certain types of blood cancers, such as lymphoma. Think of cancer cells as unwanted intruders inside your body. These intruders rely on special proteins to grow, multiply, and spread. Zanubrutinib works by blocking the activity of those specific proteins. You can imagine it like cutting off the food supply and support system for the intruders.
When those protein signals are blocked, the cancer cells struggle to grow and survive. Over time, their ability to multiply throughout your body slows down or stops completely. This targeted action helps your body keep the disease under control while you focus on getting stronger.
