A point missing from the headline:

While being vegetarian appeared to be protective overall, the scientists also found that those who follow a vegetarian diet had nearly double the risk of the most common type of cancer of the oesophagus, known as squamous cell carcinoma, compared with meat eaters. This may be due to vegetarians being deficient in key nutrients such as B vitamins, the team suggested.

So you can just choose what kind of cancer you want by altering your diet.

I feel like we're just gonna end up back where we always do, with moderation being the best policy. Don't eat too much of any one thing but eat some of everything.
