How is radiotherapy used for prostate cancer?

Many ways: Radiation is a highly effective treatment option for prostate cancer. There are many options which include: external beam radiation therapy with either photons or protons, brachytherapy with either low dose rate seeds or high dose rate brachytherapy, or stereotactic body radiation. You should see a radiation oncologist in consultation to have a discussion about these different options.

By 2 methods: Standard radiation is used very effectively in early and localised prostate cancers - this is done daily ( mon-fri) for approx 7-8 weeks. For small good risk cancers, radioactive seeds can be implanted in the prostate with very good long term survival results.
