This will be a long post sorry,please try and bear with me. We are Brits living in Bulgaria. 

Nearly 12 months ago my husband had a swelling in his left thumb. By March it had grown significantly and he was sent for an x-ray. Cyst in the bone we were told. As Covid had arrived we just left it. Fast forward to May, his thumb was huge,another x-ray. The Gps eyes nearly popped out of his head! Went to see a surgeon,who sent us to another surgeon etc etc. Eventually after an MRI cancer was diagnosed. After biopsy,it was squamous cell,with probable lung origine. Two weeks later husband had horrendous rib pain.  CT scan followed. Resulted in a laminectomy. Also a diagnosis of NSCLC. Fast forward to the present.  He started chemo/ immunotherapy treatment October. He had a PET- CT scan after 2 treatments, nothing apart from his adrenal glands lit up. His lungs now have one nodule that 7mm and is ' inactive and without dynamics compared to the previous CT scan'. I. Having to translate his notes from Bulgarian to English on Google translate. It says nothing about his thumb,which btw now has no pain and swelling is minimal,his back looks good,no metastisis anywhere else.

Im not a doctor,I know this is good. But it's stage 4 lung cancer.we both expected downhill and no progress. Stage 4 is terminal. The doctors are stumped too. Anyone else have anything like this happen?c
