Thank you Lordna for updating us, I hope your discomfort and pain soon get less.
Please don’t worry too much about the fact that three tumours were found and removed, with another ( presumably very small ) treated by diathermy ( using high frequency electric current to cut / destroy tissue ). Although it doesn’t in fact take two weeks to process and examine the tumours by microscopy, this will allow time for the neuropathologist to liase with your surgeon, so you may then be fully informed.
Best wishes for a full recovery.
