Something about it increases the chance by 10%. So that if my husband lived until his late 80's ( his unhealthy father just passed at 85) his chance would rise to 30%.
You misunderstood, or he didn't explain correctly. You are confusing absolute differences with relative differences. So, for example, if the rate of secondary bladder cancers was 1.5
in a thousand men who had prostate radiation and 1.2 in a thousand among similar men who did not have prostate radiation, that is an increase of 25%, but the absolute increase in risk is only 3 cases in
ten thousand. It does not go up
every 10 years, but may not show up for 10 years. You can get clarification about
this if you read the following.

He also explained that if he chose SBRT and the cancer came back he couldn't get more radiation.
Nonsense. His choices would include focal brachytherapy and focal ablation. Because the total dose to the prostate is only 40 Gy, salvage radiation is even safer than after IMRT. With a 97% cure rate, it hasn't happened often, and of the remainder, very few are local recurrences. However, there are only a few doctors in the US and Canada who do SBRT for high risk patients. One of them is Dr King at UCLA.
The best oncological outcomes reported for high risk patients is brachy boost therapy. I recommend you talk to Drs King and Demanes at UCLA about
this.
