hi ,my sister was unexpectedly diagnosed with a brain tumour in Jan after losing use of her arm,this rapidly within days was diagnosed as brain mets(4) from lung cancer which there had been no symptoms.
she was put on steroids to reduce swelling around brain and has just had 5 days radiotherapy to the brain and a biopsy on the lung tumour which measures 7cm by 3cms.
is it possible for the mets to spread as well as the primary?
