This kind of damage has been implicated before in the advancement of prostate cancer.

The NIH/NIST study examined four types of lesions in DNA from both cell nuclei and mitochondria, the energy factories of cells. The scientists discovered that prostate cancers cells unexposed to ionizing radiation had high degrees of free radical damage and defective restoration mechanisms. They also found that, after contact with ionizing radiation and a repair period, prostate tumor cells exhibited elevated levels of free radical damage and decreased removal of lesions.

That short-term research also discovered that the men on the low-fat seafood oil diet could actually switch the composition of their cell membranes in both the healthy cells and the cancer cells in the prostate.
