My wife was found to have a 3 mm meningioma close to four years ago. She started to take 500 mg of Curcumin (Curcuma longa) Rhizome Extract (BCM-95). In 2 years it did not grow any. Her Dr. is waiting for two years this time for another MRI. I will let you know how it turns out. The MRI will be done in August of 2020.
PS. She is a small lady that weighs only 105 lbs. Depending on your size, you may need to take more.
