Proton therapy is a modern kind of radiotherapy. But other than X-rays that rush through the body, protons unleash their energy at a predefined point that you can choose. This physical phenomenon called the “bragg peak” allows putting highly effective treatment doses into a tumour while at the same time sparing healthy organs even when they are very close by.
For prostate cancer proton therapy allows a more effective and well tolerated treatment that takes approximately only half the time to apply than conventional radiotherapy. And the long time results are unprecedentedly excellent. A recently published survey of more than 200 patients treated with protons for prostate cancer yielded a 5 year progression free survival of 99% for low and mid risk settings... Even 76% of the patients with high risk prostate cancer benefited from the treatment. And nearly all patients tolerated the proton therapy well.

Proton therapy is in comparison a rather gentle and locally highly effective procedure. Patients usually stay in a hotel close to the clinic and just walk in for their daily treatment session.
As for the example of prostate cancer it could mean that proton therapy eliminates the tumour and you can still keep your urinary continence and remain sexually active. There also is none of the risks a narcosis or operation could cause. So the therapy may be performable even if circumstances do not allow operation.
There are of course only few clinics yet that offer proton therapy, so you might have to travel far distance to get a treatment. Also you should plan a stay of a few weeks. This is necessary to keep the level of treatment tolerance high.
