I'm not able to help you with the spheres, but was wondering where you are being treated, since you are so close to NYC. I was being treated at Sloan Kettering for the first 2 years, but have switched to Fox Chase in Philadelphia for a clinical trial.
I grew up in Summit, so I know the area well.
If your schedule allows, and your father feels up to it, I am trying to start a support group. Since we are widespread, I suggested New Hope. It will be Thurs., Sept. 5. I am sending you an email through the system.
Good luck with information, and prayers for good results for your dad!
