It’s not great when a person sucks all the oxygen out of a room. When a battery does it to a tumor, though, it could be a good thing.
A tiny self-charging battery wrapped around a tumor removes oxygen from the cancer cells’ environment, boosting the power of some cancer therapies, a study in mice shows. Mice that had small batteries wrapped around their breast cancer tumors, combined with cancer therapy, showed a 90 percent decrease in tumor volume in two weeks, researchers report March 31 in Science Advances.
Solid tumors, such as those that can develop in breast cancer, often grow rapidly — so rapidly that the tumor’s
