I had the same experience as sistersu. These scans (mine was a PET) are all very well and good, but everything that looks "odd" is not necessarily cancer. Because I had horrid symptoms as well (see my autumn/winter 2010 posts) they were convinced it was recurrent/residual disease.
When I did finally agree to the biopsies - they found it was a sort of fibrosis, caused by the rads.
So sorry that you have had this worrying time, I was wondering if you had had results from your biopsy yet and really hope that you have had some good news.
Hey all… thanks so much for your replies I am hoping for the same great results!
I just heard from the doc and the biopsy has come back inconclusive… so they are having a meeting next week and they assume they will decide to just rrescan in 3 months… obviously scared and worried but trying to get on with it…
