If I have not overlooked something, then there is no statistical data that supports the notion that snus increases the risk for oral cancer.
Yes, there is plenty of data to show that
tobacco causes cancer.
Snus is tobacco!
Just because you call it something different and use against your nasal mucosa instead of your oral mucosa doesn't mean that there's suddenly no risk.
> And there is quite a bit of data on snus use, so if it did, it would have been noticed.
I can cite you dozens of studies showing no risk from smoking. It took quite awhile to demonstrate the danger of smoking, but we all know that it is now well proven. It's always hard to demonstrate long term risks in short term studies. There aren't that many people who use snus so it would be exceptionally hard to demonstrate anything in an epidemiological study.
I don't think you'd find any legitimate scientists even interested in it. It's already well demonstrated that "smokeless tobacco" products DO cause cancer, so what would be the point of studying every brand of tobacco and every orifice that you can insert tobacco into? Who would fund something like that? It certainly wouldn't do anything for your scientific career.
I could come out with ear tobacco and claim there's no data to show that it causes cancer, but what's the point? Who's honestly going to believe that it's any safer than packing it in your lip?
I don't mean to rain on your parade but Snus DOES NOT in fact raise the risk of oral cancers at all. A fair share of research can bring the light of day about that.
Show me the data then! Of course, I'll come back with 10X the number of studies showing that "smokeless" tobacco products DO cause cancer. You're not going to get around the fact that tobacco contains a lot of carcinogens and has been shown to cause cancer.
Sure, smokeless tobacco is less harmful than smoked tobacco. I don't see any reason snus wouldn't be similarly safer. Sure it may also have lower nitrosamine content also, even better. But lower levels and less risk doesn't mean it's safe or that it doesn't cause cancer.
An excess risk of dying of cardiovascular disease has been observed among snus users in a co-hort study comprising Swedish construction workers (10).
Results are contradictory regarding whether snus contributes to an increased risk of age-related diabetes.
An increased cardiovascular risk on use of snus was observed in a large co-hort study (16).
That was taken from a snus website with pretend citations. i.e. they pretended to be citing studies but had no actual citations at the bottom.
I also think it's interesting that they keep talking about oral cancer. I don't see why you would even expect oral cancer since you're putting it up your nose, not in your mouth. I could claim that smoking doesn't cause toe cancer, but WTF?
Just to break it down again... tobacco causes cancer because it contains carcinogens. When carcinogens contact your cells they mutate DNA, leading to cancer. Snus IS tobacco. Snus contains carcinogens. Therefore the carcinogens in snus can cause you to get cancer. If you know some magical way around basic facts of biology then please enlighten me.
