Associations between vegetarian diets and risk of common cancers are somewhat understood, but such data on medium-frequency cancers are scarce and oft…
As always, it’s important to actually read the source rather than just commenting.
They have a whole list of covariate variables that they examined that have been found in other studies to possible and probable risk factors for cancer. For each of the types of cancer they looked at (they looked at 365 different types) they have specific other variables that they examined that influenced that type of cancer (i.e smoking and exercise for lung).
They are examining seven day adventists only - even the non-vegetarians they were comparing against eat less meat, smoke less, drink less and are more health conscious than most Americans (from the article). This is also the biggest study of plant based diet and cancer.
They also discuss that the strongest effects are those where eating meat is a risk factor for that type of cancer (i.e cancers of the stomach).
This is a big study that suggest a strong link between diet and cancer where both the meat eaters and vegetarians are much more health conscious and eat less meat than average Americans. This method cannot establish causality, but to do that would require randomised participants agreeing to strictly stick to a diet for decades. There are extremely small or no negative impacts to not eating meat (source: article), but the health benefits from this study appear significant. As always, more data is needed - but this is just one of a number of scientific studies that show benefits to not eating meat.

Fair enough! Thanks for correcting me. That does sound like a very well designed study.
