U.S. researchers have discovered that cancer cells from patients with leukemia can be destroyed through exposure to ionized gas. In the study published in the Journal of Physics D: Applied Physics, cancer cells exposed to a four-minute stream of ionized gas were destroyed around 12 hours following the treatment. The findings may allow for the development of a dialysis-style treatment to eliminate cancer cells. Researchers are planning to study the effects of the treatment on healthy red and white blood cells.
