Talk to your primary doctor if they can get you a referral for an MRI. Insurance loves to try and deny MRIs, so I think a referral is probably required due to how expensive they are. IMO, they should be included in annual physicals since it’s one of the only (if not the only) ways to detect brain tumors early, which is critical given how difficult it is to treat brain tumors and the earlier the better.
I mean, sure, but if it detects something and there’s no reason to suspect it’s necessarily cancerous, then I’d hope doctors would recommend just keeping an eye on it and possibly scheduling periodic checkups to ensure it doesn’t continue growing. No competent doctor is going to recommend invasive surgery right off the bat.
