How much time you have depends on whether or not you choose to have the cancer treated, if you have a tumor on your tongue or elsewhere, if you have more node mets, if you have distant mets, when you get treated, how you handle treatment, and quite a bit of luck among other factors. Predicting how much time you have is impossible. The question right now is how much time do you want to have?

Regardless of any of those things, if you choose not to treat oral cancer, you are choosing a painful and horrific way to die. Please do more than consider radiation in the future. Please actively pursue treatment. You may have a chance at a cure. But, do not wait. These chances tend to evaporate quickly.

And, if you are serious about making sure you get a good shot at a cure, you will most likely need to go for traditional treatment. Alternative treatments are usually a waste of money and precious time. Eating nutritious food will be good for your body and will help it recover from treatment. But, it won't kill the cancer.

Good luck and please seek treatment.
