Has your doctor prescribed Degarelix to you or someone in your family? You probably have a lot of questions about this treatment for advanced prostate cancer. It's normal to have questions like what kind of medicine is it, what does it do, and are there any side effects. Don't worry, we'll talk about all of this simply and clearly.
Simply put, what is Degarelix?
Degarelix is a vaccine given to men with advanced prostate cancer. These cancer cells often depend on the male hormone testosterone to grow. Think of it like a fire needs fuel, and testosterone is the "fuel" for this cancer.
So, what this Degarelix injection does is very quickly reduce the body's testosterone levels. When this "fuel" supply is stopped, the growth of cancer cells is controlled, or slowed down. This is not a cure for cancer, but it is a very important treatment that helps control the growth of cancer, reduce symptoms, and make life easier.
