禦姐好，因為對DNA突變後的修複有問題，她們放療好像會導致更多腫瘤，我上麵寫的令人糊塗了，改一下。。。

Cancer and radiosensitivity
In the absence of the ATM protein, cell-cycle check-point regulation and programmed cell death in response to DSBs are defective. The result is genomic instability which can lead to the development of cancers.[25]
Irradiation and radiomimetic compounds induce DSBs which are unable to be repaired appropriately when ATM is absent. Consequently, such agents can prove especially cytotoxic to A-T cells and people with A-T.
