This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in a dish.
The short version
This was a lab test on cells in a dish, not in people.
What was studied. Researchers made tiny particles of nickel oxide with silver added. They made them using guava leaf extract. They then put the particles on rat glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary cells grown in a dish.
What they found. The particles lowered the number of living cancer cells after 72 hours. Higher amounts killed more cells. Among treated cells, 36.67% were dying. Among untreated cells, 7.39% were dying.
What this means, and what it doesn't
What it could mean: For a patient today, this changes nothing. It is a first look in a lab. The team says the idea is worth more study.
What it doesn't mean: This does not mean a new treatment is coming soon. The work was done only on cells in a dish. It was not tested in animals or in people. It is not a cure, and it may never become one.
