Waiting is so difficult--I am very sorry to hear of this. I looked up what NIHS has to say, and the standard of care is surgery within 3 months of diagnosis, and additional delays of several weeks are not considered dangerous. They say surgery, chemo, and radiation should be completed within a year of diagnosis. I have been very confused myself by being told I have a rare aggressive cancer--and then hurry up and wait. It took me months to get a PET scan and then a followup MRI. For about 90 days I had no idea if I had Stage 4 metastasis to the pancreas or not, which was suspected. (I didn't, just breast and nodes). But I guess my take away is that an "emergency" cancer is less time sensitive than a stroke or heart attack. NIHS also says that tumors growth is unpredictable, and often slows down, so patients shouldn't worry too much about delays. Frankly I find this hard to parse, but am passing it along on the chance that it is useful. When my first attempted MRI was cancelled I just kind of gave up hope and went for a nice walk with my husband. I figured I'd just be dead soon and threw out things I didn't want anyone to have to deal with and wrote up my funeral plans. However I did get treatment and am alive a year later. So wishing you the best.
