Not too high
Chances of having throat cancer
are not too high unless you are a smoker. Smoking
greatly increases the risk of cancer. If you don't smoke & have acid reflux
(you may not even know you have it) it can lead to barrett's esophagus, which is a precancerous condition.
However, only about 1% of barretts will progress to cancer. Keep in mind, cancer risks do not always follow stats. See dr if concerned.
