Hi Teresa,
Well, another Bastonian here and glad to help as well. (I'm out on Rt 128/I-95 on the Northshore).
As you may know by now, Boston is rich in treatment facilities..... and all radio-options you note are available to us locally. We are truly blessed.
I know many of us have had all the treatments available in town... from me and Cyberknife at Beth Israel... to BostonJake and Proton at MGH... to ellenvig and GammaKinfe at Providence... to jcinma and FSR.
there really isn't one particular thread in the Radio-forum here that outlines all of them but... suggestion would be... grab a glass of your favorite drink... sit back and peruse the Radiation/Radiosurgery forum. You'll see topics with specifics noted (GK vs CK or radio at a particular location or etc....) I know many of us are willing to talk as well, via email or telephone, regarding our specific situations and why we chose what we did. I know the info here can be so overwhelming, but speaking to others about the pros and cons to their paticular situations may be of help. Talking one-on-one sometimes may help prevent that overwhelming feeling...
Hang in there... and please keep an eye open in the "AN Community" forum for our next ANA Website New England Brunch, usually held at Maxwell Silverstein's in Worcester. Should be next month... would love to have you join us.
Phyl
