Kathryn, this is the time for a DEEP breath. You are very fortunate to have a dentist who is wise enough to send you for a biopsy. If you have read around this forum, you will have encountered the saying "It ain't cancer 'til the pathologist says so." There are two things to be thinking about now: 1. Spots on x-rays can be many things not cancer; and 2. If it is cancer, the fact that you are discovering it sooner rather than later is very much in your favor. So breath deeply and try to keep yourself on an even keel until you have some facts. A diagnosis of cancer is NOT an automatic death sentence. I would suggest that you not read more at this site unless and until you have a diagnosis. What you read may not apply to you, but will certainly scare you. Right now just concentrate on being as calm as possible. If you do have a positive diagnosis, come back and we will answer all your questions and give lots of advice, solicited and otherwise. Bottom line, it is not the time to panic. Let us know what you discover. We will be thinking about you.
