oesophageal cancer in healthy woman.

Hi, my wife just had an endoscopy as she’s been struggling to swallow for a few months, and they found a tumour at junction to stomach which is now being tested. Next week is the CT. 

We have been told it’s 90% chance of cancer.

shes only 49 and never smoked or drunk.

is there anyone else in a similar situation?

im terrified.
