This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in mice, not in people.
The short version
Scientists made a spray that lights up tumor cells during surgery, but it has only been tested in mice.
What was studied. Researchers built a new spray called SEQTAC. They tested it in mice with breast tumors and with brain tumors called glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary.
What they found. The spray was taken up by tumor cells and turned on inside them. It then gave off light, so the tumor edge could be seen and removed. After surgery, a laser made the spray attack any tumor left behind. The mice had less tumor come back, and they lived longer.
What this means, and what it doesn't
What it could mean: Tools that show the edge of a tumor may help surgeons take out more of it. Leftover tumor cells are a real problem in brain tumor surgery. This spray is one early idea aimed at that problem.
What it doesn't mean: This does not mean a new treatment is ready for people. The work was done in mice, not in patients. It has not been tested for safety in humans. No one can ask for this at a hospital today. It is not a cure, and it is likely years away from normal care, if it works at all.
