My chart says I got 20 gy of post-op SBRT to my middle spine (T3, well above the diaphragm) in 2021, after the surgery to debulk the lesion. It's very important that you stay perfectly still when they're working near so many vital organs. For me, they made a custom cage that held my head immobilised during radiation.

It was very uncomfortable, but on the bright side, I'm not aware of any side-effects from that round of radiation therapy.
