i had a nasty fall at work and banged my head on an operating table at great Ormond street hospital, my brain coned and the nation hospital for neurology and neurosurgery took a part of mt skull out for the swelling. It was hit and miss but I came through and made an excellent recovery. When the time came to replace the skull the Mri shown a tumour. When they debunked what they could (it was quite large) it was a grade 2, every 3 months at uclh I have an mri to check and a growth made the surgeon take a biopsy and unfortunately it was a grade 4. So I hade radio therapy and chemotherapy and now have 3 monthly mri's
