Kristi hello from a former neighbor, used to live in Maryland Heights. I hope I can answer a couple of your questions. Don't know about the chances of the spot being cancer, Spot on my tongue didnt' exactly change day to day, just over a period of time. Good idea to have it checked though. While it's tempting to just say "take it out" at the first go round, the biopsy can be done as an outpatient procedure, just a small cut. Taking the whole spot out is a little more extensive and would probably require in-patient surgery.

As far as doing treatments while pregnant, just had an intersting conversation with my oncologist last week about this very subject. Wife and I are trying to "get pregnant" and I asked about how the radiation/chemo effected that chance. He said there are some cases where they'e had to treat pregnant women, and had no ill side effects as far as the baby is concerned. Radiation is pretty localized it seems, and I think they can adjust the chemo dose to compensate for the pregnancy.

I would think the latest you would get results back is the following Monday, depending on the lab and hospital you are dealing with. Here it was 3 days for report, and the pathologist is in house at the hospital. I'd find out from the oral surgeon exactly what the schedule is for the pathology report to be done.

Good luck, and try and stay calm.
Bob
