WebApr 30, 2024 · Both the benefits and dangers of ionizing radiation for treatment of cancer come from the fact that radiation kills cells. Factors that alter cell killing efficacy were summarized long ago by the “4 Rs” of radiobiology: 1. Repair: Radiation produces both lethal and sublethal damage. WebRepair. repair of sublethal damage occurs within hours of radiation exposure in normal and tumor cells. is oxygen dependent because a portion of tumor cells are thought to be hypoxic therefor making tumors incapable of repairing sublethal radiation damage as efficiently as normal tissues. Reoxygenation. applies only to tumor cells, which is the ...
