I thought rather than go through [non-surgical treatment for prostate cancer] which can be through monitors and blood tests and maybe more, having to take pills or some kind of medication for your prostate rather than go for the operation, I says, ‘Doing insulin five times a day I think is becoming an awful lot and then having any more of a load on top of that’, so that was the main reason. This evidence concerns the gene INS and prostate carcinoma.
