This was tested in people. That is the most reliable kind of research we share.
This study watched real surgeries and compared surgeons, so it did not test a new treatment.
The short version
Patients operated on by a surgeon in their first years of solo practice did about as well as patients operated on by an expert.
What was studied. Doctors at one hospital tracked 352 awake brain surgeries for glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary between 2022 and 2025. 101 of them were done by a surgeon in the first four years of working on their own. The rest were done by a senior expert with long experience in awake surgery.
What they found. In awake surgery, the team uses a small electric current to find brain areas and wiring to protect. The team recorded 1,158 responses to that current. The amount of tumor left behind and how patients functioned afterward were about the same in both groups. The newer surgeon found one deep bundle of brain wiring less often, mostly in tumors at the front of the left side of the brain. The two groups did not have the same mix of tumors. The newer surgeon had fewer slower growing grade 2 gliomas (46.5% vs 65.3%) and more glioblastomas (27.7% vs 6.4%).
What this means, and what it doesn't
What it could mean: If a surgeon early in their career is doing your awake brain surgery, this study is reassuring. Patients came through about the same either way. The study also points to a few mapping skills that take longer to build, which can help shape training.
What it doesn't mean: This does not mean every surgeon is the same, or that any one surgeon is right for you. It was one hospital, one newer surgeon, and one expert. The two groups of patients had different kinds of tumors, so they are not a perfect match. This study did not test a new treatment or a new drug. It is not a promise about how your own surgery will go, and it is not a cure for a brain tumor.
