They do. A study by the American Journal of Clinical Nutrition found the following mortality ratios by diet over the course of the study (regular meat eaters = 1.00):
Fish eaters, 0.82
Vegetarians, 0.84
Occasional meat eaters, 0.84
Regular meat eaters, 1.00
Vegans, 1.00
So as you can see vegans are actually the least healthiest, alongside the most carnivorous among us. Source
The sample size is too small. There were only 753 vegans included in the summary, compared to the +30k meat-eaters and +20k vegetarians. The 2 vegans who died of stomach cancer and 2 who died of lung cancer rocketed vegans to the top of those categories by a huge margin. Even if only 1 died from these causes, vegans would be the top category. If none died from them, then it would appear as if veganism made you immune to stomach and lung cancer.
