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, not in people.
The short version
An extract from a yellow fruit killed glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary cells in a dish but left healthy cells alone.
What was studied. Researchers made a liquid extract from the yellow fruit of Psidium cattleianum, a plant from South America. They put it on two glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary cell lines, C6 and U87MG, and on healthy brain and skin cells, for 2 to 72 hours.
What they found. The extract cut the growth and survival of the glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary cells. It also lowered how many new cell colonies formed. In the C6 cells, it slowed how far the cells moved. The healthy cells in the test were not harmed. Tests showed the main parts of the extract were ellagic acid, catechin, and gallic acid.
What this means, and what it doesn't
What it could mean: It hints that something in this fruit may act on tumor cells and spare healthy ones. That is a reason for scientists to keep studying it. It is not a treatment, and nothing here tells you to eat this fruit for a tumor.
What it doesn't mean: This does not mean the fruit treats brain tumors. The work was done on cells in a dish, not in people or animals. No one took this extract as a medicine. Many things that kill cancer cells in a lab fail later in people. This is very early science and it is not a cure.
