Meningiomas

Anyone out there like me? Diagnosed with secondaries in my pleura september 2014. Started feeling dizzy after leaving hospital after op… CT MRI on head. Wham Brain tumours. Meningiomas x 2. Awaiting op for removal of big one behind my eye… I’ve googled and googled and there is a link between oestrogen + BC and M’s but not a lot of information. Anyone?
