In reply to ThunderCat:
Sorry to hear that, you and your family must be very frightened and worried.
It should take a few weeks for the results of the biopsy to come back to your mum and the family.
once that’s back you will mostly know what you are up against.
they may want to do a CT scan as well as the biopsy which might take a few weeks too, a CT gives more information than the X-ray she has had already.
After those two tests are known the MDT ( multidisciplinary team) would discuss and decide the best options and let you know what is happening.
At the MDT will be specialist doctors/surgeons/x-ray specialists and experts at looking at biopsies under microscopes as well as specialist nurses.
Until they and you have that information it’s all guesswork and many diagnoses are possible including good ones.
Try and get to see her and have a hug if you can though I know you said she’s a long way away.
best wishes
