The agony of waiting! I know it well. It's hard the first time. First of all there is good reason to believe there is no cancer, secondly, you can use this time to treat and spoil yourself. It it is cancer you will have some treatments which might not be nice so try to do things you really love over this time. Another thing is to avail yourself of a counsellor. They are used to dealing with people going through this sort of stress. You aren't alone. There are thousands of cancer patients out there going through the same thing and many of them online, all of them knowing that uncertainty and being in limbo is a major cause of stress. We are with you.
