Actually clinical trials were started some time ago (in Europe) about receiving RT more than once and surprisingly the collateral damage was not as bad as they expected.

IMRT, because of it's highly targeted nature, can be repeated if it is not exactly at the same site.

PBT may be the treatment of choice for recurrence since it has little to no collateral damage.
