He proposes that the cell-killing ability of currently used anti-cancer therapies – toxic chemotherapeutic agents such as Taxol as well as radiation treatment – is mainly due to the action of ROS to induce apoptosis, or programmed cell death. This would explain "why cancers that become resistant to chemotherapeutic control become equally resistant to radiotherapy." The common feature would be their common dependence upon a ROS-mediated cell-killing mechanism.
