My question is if I decide to do radiation in that area how would I be sure one of the other 11 needles didn't miss a cancer and those areas wouldn't get treated? Would another biopsy be required at the point?
Radiation does not work that way, and for exactly the reason you suppose. The biopsy is just a random sampling of 12 tiny cores out of your entire prostate. When they find cancer in one core, it's almost certain that it's also in other places too. For that reason, radiation therapy is always given to the whole prostate. When a treatment is given to the whole prostate, it's called "radical" treatment. Primary treatment by radiation or surgery is always radical treatment.
There's another kind of experimental treatment called "focal" treatment, but it uses a different kind of therapy called "ablation." You are right that if you opted for "focal ablation" they would have to do a new set of biopsies, usually guided by special kinds of MRIs called multiparametric MRIs or by a special biopsy technique called "transperineal template mapping biopsy."
I think surgeons want a few months to pass after the biopsy to clear the blood and scar tissue, The more important waiting period is the time it takes for you to learn what you have to know to make an informed decision.
