Prostate cancer usually needs testosterone to grow. Hormone therapy aims to stop:

  • the testicles from making testosterone

  • testosterone from reaching cancer cells

Bone loss is a common side effect of hormone therapy. But how much bone loss you might have varies from person to person. And not all hormone treatments cause bone loss. 

Your nurse or doctor will tell you if they think you might be at risk of bone loss. Especially, if you are at high risk of having problems with your spine.
