What are the odds I have oral or throat cancer?

Low. You have not provided much information. Age, use of tobacco and alcohol, oral hygiene, hpv infection, oral plaques or ulcers, any mass or lump? If you do not use tobacco or drink, the risk of oral or throat cancer is very low.
Life time risk. Your life time risk to develop oropharyngeal cancer is between 1 to 69 for male and 1 to 149. http://www.cancer.org/cancer/cancerbasics/lifetime-probability-of-developing-or-dying-from-cancer.
To vague. Would need more history. Your age, sex, race, family history. Any exposures , do you smoke., any symptoms or physical findings etc. Ask again and be more specific.
