Awaiting PET

Hi all! I am a young mum of 2 who has recently been through surgery following my diagnosis. I had estrogen receptive, her 2 negative stage 2 cancer. The surgeon removed 5 nodes, one of which had a one cancer cell. I have been referred for chemo but prior had to have body staging to rule everything out. Of course as it happens there is now a query around 2 lesions on my spine. I have to have a PET scan as the radiologist is unable to conclude if it’s a benign change or not. I am trying to stay positive but I find it very difficult. I can’t see past this and find that I now am fixated on this is definitely a bad sign, even though my oncologist herself isn’t that convinced. I don’t know what I am looking for but I just needed to write this down.
