Each case is unique so our physicians would need to review your records. The nice thing about proton therapy is that it is so precise, it does allow for retreatment with radiation to the same location - unlike traditional x-ray radiation. Our physicians would just need to determine the optimal length between doses.
It is a case by case situation, most dependent on the amount of radiation you have already received in the target area, as there is a limit the body tissue can take before damage. You should contact them to consult your specific case.
I would give them a call. They will definitely call you back or also can email you.
