This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at real patient records rather than running a trial, so this guides discussion but does not prove the operation adds time.
The short version
Surgery to remove brain tumors was linked to longer life, but much of that may come from doctors choosing the healthiest patients for it.
What was studied. Doctors looked back at hospital records for 157 women with breast cancer that had spread to the brain, treated from 2006 to 2022. They compared people who had brain surgery, called a craniotomy, with people who did not.
What they found. Craniotomy was done in 37.4% of the patients. Those who had it were more likely to be alive at 30 months, with a 30% survival rate. When the researchers matched patients with similar health to make a fairer comparison, the benefit got smaller. That suggests patient selection explains a lot of the difference. Sixteen patients lived less than 6 months. Of those, three, or 18.8%, died within 30 days from problems related to the surgery. The rest died because the cancer itself kept spreading.
What this means, and what it doesn't
What it could mean: Brain surgery is already an option for some people whose breast cancer has spread to the brain. This study suggests it may help most when a person is otherwise in decent shape and has a single brain tumor. It also suggests that having had radiation therapy goes along with living longer. Careful selection matters, and your team will weigh your overall health and how much cancer is elsewhere in your body.
What it doesn't mean: This does not mean surgery adds years of life for everyone. The researchers only looked back at old records, so they cannot prove surgery caused the longer survival. Much of the difference may simply be that healthier patients were the ones offered surgery. Surgery also carries real risk, and a few patients here died from surgery complications. This is not a cure, and it does not change the guidance you get from your own care team.
