Welcome.
There are side effects to all treatment for prostate cancer at this time. Doing nothing also comes with a price.
There are lifestyle choices and medications that can improve your dealing with the treatment side effects. Not all of us experience the same intensity of side effects.
Your task is to learn as much as you can about
all of the options, then make your best choice. It is not so much age, rather, it is your overall health, fitness and emotional strength that matters.
I had a trail friend who got brachytherapy for a bothersome PCa when he was 87. Yes, the side effects bummed him out for a while, but those passed and he made it to 94 years old in relative comfort, died peacefully in his own home with a big smile on his face.
