Yay! As suspected the tumour is cold on the PET scan so the new wedge shaped shadow is Fibrosis (scarring) afterall. The fibrosis will never get better, it is there for life. I will take that result, I can live with the scarring but not cancer. I still have that hot spot in my bowels so a colonoscopy has been re-referred, the last one got purged from the system probably because of Covid. The Bowel Cancer screening, with the stick, came back as negative a couple of months ago. All in all I am happy with the this morning's result.
I will have another appointment in 6 months, preceded with an X-ray.
