Cancer Risk for the Overweight?

MSNBC just announced Thursday that, "Being obese or even overweight may increase a person’s risk of developing up to a dozen different types of cancer." The study suggests this is "only a link, that there is no definitive proof that the fat itself causes cancer."

I'll stick my neck out here. It’s not really about carrying excess "fat"  in my opinion. Most overweight people are eating too much of the wrong kinds of food (too many refined carbohydrates, coffee, alcohol, processed foods, etc.) with little nutrient value and not enough of the healthy foods (like fruits and vegetables which studies are pointing out their protective properties for preventing cancer and numerous other diseases).

Additionally cancer breeds in an acidic environment of our bodies. What causes an acidic environment in our body? – it's all those unhealthy foods in excess! I honestly believe there will be much stronger cancer "links" to obesity as more and more studies are done.
