Though the effects of radiation can be hard to deal with for individuals suffering from cancer, oncologists acknowledge that it’s one of the more effective ways in which to combat the second most common cause of death in the U.S., according to the American Cancer Society. Now, new research indicates that gold particles found in precious metals may play a role in making radiation therapy more effective, potentially lowering the radiation needed to rid the body of cancerous cells.

According to newly released findings from Brown University and the University of Rhode Island, exposing cancer cells to gold nanoparticles can intensify the degree to which these cells are destroyed when combined with radiation.

Publishing the findings in the medical journal Proceedings of the National Academy of Sciences, Michael Antosh, the study’s lead author and assistant professor at Brown’s Institute for Brain and Neural Systems, noted the lab tests were promising.

«This study was a good proof of concept,» said Antosh. «We’re encouraged by our initial results, and we’re excited to take the next step and test this in mice.»

After additional testing done on lab mice and perhaps clinical inquiry some time in the future, the hope is that the effectiveness of gold nanoparticles will enable doctors to use less radiation during cancer treatment, sparing people from the harsh side effects, which can include fatigue, abdominal discomfort, shortness of breath and soreness.
