London, Nov 9 (IANS) Magnetic force can help
treat prostate cancer in men, say experts.
Unlike chemotherapy and radiotherapy, the treatment can kill cancerous cells
without harming healthy tissue, Daily Mail reported Wednesday.
Researchers at the University of Sheffield said it is effective for most
advanced forms of the disease.
Prostate cancer is the most common form of cancer in men. There are around
37,000 new cases a year and 10,700 deaths.
When prostate cancer develops, some of the white blood cells, called
macrophages, flock to tumours to try to fight them.
However, because these tumours grow and spread so rapidly the blood cells are
unable to keep pace.
To speed up their action, the researchers have injected the cells with
magnetically-charged nanoparticles, each one 1/50th the width of a human hair,
according to the Mail.
This magnetic force enables the cells to move much more quickly around the body
Early lab tests have shown that the white blood cells can reduce numbers of
cancerous cells. However, researchers stress that the treatment is in its early
stages. They hope to carry out trials on humans within the next five years.
