Intestinal Metaplasia: What do you do to lower the risk of cancer?

I was sent to an Oncologist who told me I have a better chance of getting prostate cancer than stomach cancer from this.
He said the 2 worst things to do are smoking and drinking, family history plays a role, and just plain bad luck.
I drink Healthwise low acid coffee in the morning.

I have some abnormal cells too along with chronic gastritis, I also had H Pylori too which is a risk factor. Get checked for that. I also have Barretts Esophagus which is in remission due to my taking of PPI's and a strict low acid diet. NO booze, No smoking. No soda! Drink water, decaf green tea, unsweetened almond milk which is alkaline. No mexican, Italian or FRIED FOODS! It's scary thinking about stomach cancer.Do what you can to put the odds in your favor.
