The condition and the treatment
When prostate cancer has spread to another part of the body, usually the bones or lungs, it is called advanced or metastatic prostate cancer. In most men with prostate cancer, the hormone testosterone makes the cancer grow faster. So prostate cancer can be treated with drugs that make the body produce less testosterone, or react to it in a different way. After a time, the cancer stops responding to such treatment – this is known as 'hormone-relapsed' cancer.
Enzalutamide (also known as Xtandi) works by stopping testosterone from getting to the cancer cells. This prevents prostate cancer cells from growing.
