Was wondering if i chew tabacoo once a week will i get mouth cancer?

Yes: Increases your likely hood of the disease.

You might..: All forms of tobacco, especially smokeless tobacco increases your chances every time you use. It's like playing the lottery, the more you play, the more chances you have of winning.... But in this case in a bad way. The sooner you stop the better your odds of saving your jaw, your tongue, your face, and even your life.

Risky business!: No one can give you a definite answer nor a percentage chance of getting cancer from chewing tobacco. What we do know is that all forms of tobacco are carcinogenic. Some people are more sensitive than others to carcinogens and there are other risk factors as well. For instance, smoking and alcohol greatly increases the risk. Your choice, your mouth, your life. Is it really worth it?

Perhaps: Perhaps.Less that chewing daily. Worth the risk? See oral surgeon or ENT doc if you have any of these symptoms: Persistent mouth sore, persistent mouth pain, a lump or thickening in the cheek, a white/red patch on the gums, tongue, tonsil, or lining of the mouth, a sore throat, hoarseness or feeling that something is caught in the throat that does not go away, difficulty swallowing/chewing.
