Is it possible for meningioma that have not shown a growth in size during the past 4 months to be left untreated?

Meningioma growth: Meningiomas in some patients are indolent tumors and may not show changes over years, even without treatment. Ask the radiologist for precise measurements of the meningioma; your MD should be doing this. I am perplexed at many of the questions posed on this site & wonder what are physicians doing for their patients, and why are not these questions being answered by the local medical doctor.
