A bit unsatisfactory.
Is it a meningioma or not........if it is, then her prognosis is excellent and would not need radiotherapy or chemotherapy.
Upgradeable? What doe this mean? Does it mean that it may not be a meningioma? I would have a word with the consultant neurosurgeon for an explanation of the meaning of "upgradeable" and also ask what he means by the biopsy was "no good."
Very unsatisfactory state of affairs, but no, at this stage i wouldn't seek a second opinion.
