Mean values of estimated hazard rates and life years lost (LYL) attributable to radiation-induced secondary breast and lung cancer for the ten medulloblastoma patients based on the VMAT plans. Data is shown for attained ages up to 90 years after which we assume that the hazard remains constant at the level reported for the 85+ group in the SEER registry. The LYL curves are left-shifted compared to the hazard rate curves illustrating more life years lost after an event occurring at younger age. Despite similar hazard rates for contracting breast and lung cancer, there is a large difference in LYL attributable to breast and lung cancer as a result of the different prognosis of the diseases.
