Fighting for Better Cancer Detection

October 28, 2016

A mammogram’s ability to detect tumors at early stages has made breast cancer one of the most treatable forms of cancer. Still there are almost 50,000 missed diagnoses every year. Engineering professor Ryan K. Roeder has devised a way in which gold nanoparticles can be injected into the breast and attach to indicators of cancer, so they can be clearly seen.
