I have a radiological occurrence of a meningioma in the sagittal sinus following surgical removal 2 years ago on the cerebellum. Now on watch and wait til Jan 2019 with radiotherapy being on the cards. Surgery also another option.I had radiesse into the chin a few months ago (before second diagnosis) but would ideally like a little more. Also considering lip filler.Would either of these procedures interfere with the effectiveness and treatment of radiotherapy(probably gamma knife) in the future?
