Vaping cause mouth cancer?

[Giantfan]

recently released research:

relationship between nicotine and OPNc expression in the pancreas has been identified
effect of nicotine and the nicotine-derived nitrosamine NKK on normal lung epithelial cells has been identified
effect of nicotine in stimulating the progression of tumor growth, through a cyclooxygenase-2–dependent pathway has been identified
effect of nicotine in increasing expression of the gene FOXM1 in the mouth, has been identified
Nicotine exposure heightening the expression of the nicotine receptors, leading to increased cell proliferation and inhibition of apoptosis in lung and breast cancer has been identified (apoptosis is the process where by 'sick' or precancerous cells pretty much commit suicide and die - inhibition of this process promotes agressive growth of these sick or pre-cancerous cells into tumors)
the nicotine byproduct NNAL and another byproduct called cotinine, on the risk of developing lung cancer has been identified

Hope this helps!

I know of this, but cells need to already be damaged and maybe even cancerous before nicotine will have that effect.

Just look at the Swedish snus example. Snus has almost no relationship with oral cancer. I think 20% of Swedish men use snus, and yet there are no statistics that support any increase in disease. (besides a slight increase in pancreatic cancer, which is tiny. And, it isn't even that convincing since a lot of the people in that study were former smokers).

Sorry, but speculation discussions like this play perfectly into the hands of all those -- and they are legion -- who oppose keeping e-cigs legal. The topic headline alone is a shock.

Why give the enemy ammo? If you have a real concern -- QUIT.

Well said!! thats all I got to say....you took the words out of my mouth

I agree. It's a stupid thread and it should be thrown out.

I'm no doctor, but from what I understand, it isn't the nicotine you've got to worry about as much as the possibility of the heat from the vapor causing oral cancer, just as much of a risk as smoking an analog. Others can chime in and correct me if I'm wrong

Are you implying that the heat from the vapor can cause oral cancer? What about the heat from hot tea or coffee? Certainly the temp is higher than that of the vapor, at least in my experience with my 510. Sorry, but the logic of this thread is escaping me.

im going to have to disagre on account that this is a forum geared towards discussion and learning on these products... the title was structured as a question and it deserves all response therein

sure e-cigs are going to cost big tobacco alot of money, but that doesnt mean that we should throw someone's topics and concerns out just because we love our habit

smokers react the same way when someone challenges their beloved cigarette.

i believe all things should be discussed openly, good and bad.

Not like I'm going to quit because of a "chance" - There is a "chance" I die in a fireball car crash on the way to work, doesn't mean that I'm not going to work does it?

Just wanted to get input on the likelihood of it because I wasnt sure if nicotine in it self causes damage to the membranes absorbing it in your mouth.

Wow TB, really? Is this board only for super good happy vaping thoughts? I thought it was an exchange of information. I think the OP had a real concern and the posters were talking it out. WTF?

No, Nicotine does not cause cancer, chemicals and tar in tobacco smoke causes cancer

this is from a doctor, click here:Does nicotine cause cancer?

1. The nitrosamines in PVs (from the nicotine) were found in TRACE amounts. No more than found in nicotine gum. If it was known to cause cancer at those levels, there would be a lot more concern over NRTs. At those levels, it has been deemed no more harmful than the nitrosamines found in harmless levels in other approved products.

2. The studies of nitrosamines in nicotine showed that they don't activate on their own. It's in conjunction with other factors, factors which don't occur in PV use.

3. Propylene glycol HAS been studied and is considered non-carcinogen.

4. That leaves the flavorings. Those are every day food flavorings - used in millions of food products. If those cause cancer, then there is a greater problem than using PVs to be concerned about.
