Surely it's better to reduce cancer risk by taking foods/supplements that actively reduce tumours rather than messing with our finely tuned hormone system? When I had cancer I used broccoli sprout juice and alkaline forming foods and this was enough to get rid of my cancer. I now follow the same protocol everyday and remain cancer free, years on. It doesn't have to be broccoli sprout juice - I know of people who used curcumin to heal from cancer. I personally don't believe that we should be even talking about 'risk' of cancer because that is putting everyone into the same bucket so they can be categorised when everyone is different and what works for one does not always work for another. I also think we should go back to basics and look at cultures that are virtually free from cancer - the vasty majority of these follow a simple natural diet free from processed foods and sugar.
