Generally a meningioma is benign, not cancerous. From the link to Sinai Hospital, they state:
"Meningiomas are a common type of brain tumor that develops slowly in the meninges, or the area that covers and protects the brain and spinal cord. Most meningiomas are benign and can vary greatly in size and location."I think what is meant by 'non-metastatic' is that it does not spread and therefore benign, but you'll have to check this out.
I was operated in 2010 for this kind of benign tumor, a rather large one (4 in x 2.5 in x 1.5 in), to surgically remove it, but later another tumor in the same region was detected in 2021, a regrowth about one inch in diameter. It was treated with the CyberKnife X-radiation non-surgical procedure, which resulted in stopping its growth and shrinkage of it.
Thank you for finding this link and posting it. The idea is that the medical drug may apply in my case if another develops. I am very grateful for your diligence in identifying such successes in medical research!
I have an appointment today with the expert doctor who operates the CyberKnife X-ray machine (Sept. 2021) for dealing with a meningioma that grew since the surgical removal of one in 2010. I had an MRI last week on which this conference will discuss the results. My concern is to see if there is regrowth or occurrence of any others.
