I am in the same situation. My wife and I were at Mayo Clinic, MN last week to review a recent MRI showing my meningioma tumor measuring 3.6 x 2.7cm . It was first discovered by accident in 2017 and measured 2.5 x 2.5 cm. Since we don't know the growth pattern and I am also not showing any symptoms, we are going to wait until next year to re-do a MRI and see what additional information surfaces. Good luck to you.
