My dad got radiotherapy treatment and hormone injections for prostate cancer last year which was a success however at his routine check up they've discovered he now has it on his vertebrae at the top of his back/bottom of his neck and also on his lymph nodes in his groin,today after discussing with his consultant they've decided to go ahead with SBRT.......I'm worried sick but putting on a brave face for his sake because he doesn't like a fuss,I know everyone reacts differently to treatment but what should I prepare myself for during my dads treatment please?
