Scientists at the University of Oklahoma Health Sciences Center have developed a microwave technology to treat late-stage breast cancer.
The new technology heats the breast tissue and compresses breast cancer tumours to increase the capability of chemotherapy.
OU Cancer Institute researcher Dr William Dooley said the therapy is a major advancement for women with later stage breast cancer.
"Right now, most patients with large tumours lose their breast. With this treatment along with chemotherapy, we were able to kill the cancer and save the breast tissue," Dooley said.
