Meningioma and Cavernoma: Stressed Waiting and Watching

Never ever thought I'd be in a discussion like this. But. No surgeries ever. "Healthy as a Horse." 62-year-old female. Diagnosed with "left paramedian posterior frontal convexity meningioma (16mm x 16mm x 10mm). Small left cerebellar cavernoma." No symptoms. Wait and watch. Pins and needles. Stressed beyond words. Having another conversation with PA in Neurosurgeon's office because I have more questions. Is there a relationship between meningiomas and cavernomas (both found incidentally)? I have sometimes...a swelling shaped like a football on my forehead and wondering if it's related. Mainly I'm numb from diagnosis. Thanks for being here. It's a funny life....
