I have had radiation as a child when they didn't know how dangerous it was. I have had surgery for a golf ball size meningioma. They couldn't remove all of it because it was in a dangerous spot. Don't know when I developed another small one. Even tho I had a MRI every year no one ever mentioned another one. It is starting to grow and they recommended the Gamma Knife. I am going to see what Mayo in Rochester has to say. I would like them to do the procedure.I also had thyroid cancer 20 years ago. Worked in a hotel and had a group of researcher from all over the world who were studying meningioma and the connection of thyroid cancer and the tumors. I joined their study group and gave my DNA.
