This was tested in people. That is the most reliable kind of research we share.
This is a look back at care people already received, not a test of a new treatment.
The short version
Most older people with this kind of pituitary tumor were watched, not operated on.
What was studied. Researchers looked at 673 people age 65 and older in Sweden who had a large pituitary tumor that does not make extra hormones. Their doctors chose to watch the tumor instead of operating.
What they found. During follow up, 6.7% of the group had surgery. Tumor size, hormone levels, and vision stayed steady over time. People who had lost side vision at the start were more likely to have surgery later.
What this means, and what it doesn't
What it could mean: For older adults with this kind of tumor, watching and waiting may be a reasonable plan. Regular check ups still matter, and eye checks look especially useful. Vision loss at the start, not the size of the tumor, was tied to needing surgery later.
What it doesn't mean: This does not mean surgery is wrong or that no one needs it. This was a look back at records of care people already got. It was not a trial that tested one plan against another. It covers one type of pituitary tumor in people age 65 and older, so it may not apply to other brain tumors. It is not a cure and it is not a promise about your own case. Your own plan is a talk to have with your doctor.
