You should not let geography limit your dad's treatment options, though there may be other reasons (insurance, finances associated with travel, etc.) that restrict your choices. If that's the case, where in NJ are you?
If you are in South Jersey, several OCF members have been treated at Fox Chase Cancer Center and the Hospital of the University of Pennsylvania, both in Philadelphia and both well-regarded comprehensive cancer centers. Memorial Sloan-Kettering has an office in North Jersey, though surgeries are still done at the main hospital in NYC.
