Every hormone can potentially TRIGGER specific types of cancer that are specifically triggered by that hormone. The cancer itself already exists before the hormone triggers it, the hormone doesn't CAUSE the cancer, it just triggers it to activate. It turns benign could-be-cancers into active killers. But these same hormones are necessary and trigger good things in the human body as well and primarily. It's just due to the nature of cancer that some forms can be triggered by something that is normally good and healthy.
The correct answer to preventing cancer is to consume foods like garlic, and herbs like (currently illegal in most places, thank the pharmaceutical industry) marijuana. You don't need to smoke the latter, unless you REALLY want to, it's actually even better for you (in highly controlled doses) eaten.
You also want to avoid the real cancer causing agents in our environment as much as possible - toxins that get in our food supply intentionally or otherwise the biggest of these. To do that, go all organic and non-gmo. Also avoid an all-vegan or all-meat diet, both are leading causes of cancer due to stress caused by vitamin imbalances.
You can't do too much about what's in the air you breath, but consider getting a high-quality water filtration system. If you have city tap water, you can use a ZeroWater filter for all your drinking and cooking water, it is very effective at removing all inorganics, which tap water is left full of but does effectively kill organic pathogens. If you're using well water, then you'll need to install a customized RODI system that includes organics filters such as a UV light filter. Regardless of your source of water, do NOT use any other brands of filter besides ZeroWater if using something other than reverse osmosis with dialysis and additional filters for organics. Only ZeroWater currently uses their own patented filter system that is proven to remove all inorganics, thus the name. RODI does the same thing, of course, but costs significantly more money to install and has waste water, adding additional use overhead. The only reason to use RODI over ZeroWater is if you need to install filters for organics, which ZeroWater cannot filter.
