Reirradiation, in combination with systemic therapy or biologicals, in recent years, has become a popular option for locally recurrent cancers and for infield second malignancies in cases where surgical salvage is not feasible. However before embarking onto such a course of second radiation a systematic approach is needed to avoid undesirable consequences and to gain meaningful advantage in terms of survival and local control. An decision making approach for common cancers where re-irradiation is commonly used like the head and neck cancers, the gliomas and in cases of gynecological cancers has been discussed. Proper selection of the cases and the choosing the intention for re-irradiation is probably most important initial step. Care of the details of the initials course of radiation like the dose fractionation schedule, volume irradiated, dose to the Organs at risk along with patient's present general condition is of utmost importance. Issues like dose memory, threshold time interval, maximum effective cumulative dose etc are still areas of research and their importance in each individual site needs to ascertain in future. Finally, the aim is to have a perceived benefit over the potential of harm in a successful course re-irradiation.
