I chose PT because I did not want a 2nd crainiotomy done elsewhere (the first one had infected hardware which had to be removed, continuing issues, with a wait and see situation).
PT treatment: I chose Mayo Clinic in MN because I researched options to crainiotomies and they accepted my insurance as another Mayo did not and I had lived in MN so knew the area. Mayo is ranked #1 for many medical issues. Doctors are from all over the world. Because treatments are very short (a few minutes a day) on a week-day daily basis, I stayed in Rochester, MN for the 5 weeks of treatment rather than fly back and forth, which would have been impossible on a daily basis. Excellent team. Feel absolutely nothing during treatment. Head is immobilized, wearing a made-for-patient mesh mask which locks down to table. Four angles of beam go into head from 4 different directions. Table turns each time. You have the option to have music of your choice playing, warm blanket. No drawbacks so far as I can determine. PT stops growth, does not destroy it, so the meningioma is still there (unlike when it is cut out during a crainiotomy). Follow-up MRIs continue every 6 months, which can be done locally, or back at Mayo.
Each situation is unique. I hope this gives you some insight. Best!
