Welcome. I understand the flurry of activity in preparation for the unknown but suspected bad experience ahead.

Having received a diagnosis only a few days ago you are entitled to spin for a bit. But the most valuable way to spend time is to start reading all you can on the forum here first to get up to speed about the realities of what you face.

Knowledge is power and the more you know and are informed the better prepared you will be to understand what is happening and asking informed questions about various options, side effects, treatments, etc.

There is absolutely no doubt in my mind that an afternoon spent reading about chemo treatment and radiation treatments for oral cancer patients will pay off far more than cutting down some limbs outside.

The sooner you come to grips with the reality and start getting educated the better equipped you will be to extract all this forum has to offer.

Good luck.
