I am happy to read that the Doctor is convinced that it is not cancer but has organised the MRI in any case. Even after all my requests I have never had an MRI, CT or PET.
My doctors tell me that it is not necessary!
Even for peace of mind it will be good for your daughter to have the MRI.
Best wishes for the outcome of the test.
