In the United States alone, there are nearly 240,000 breast cancer diagnoses each year, and one in eight women will develop breast cancer at some point in her lifetime. To date, mammograms are the best diagnostic technology for breast cancer. A mammogram’s ability to detect tumors at early stages has made breast cancer one of the most treatable forms of cancer, but there are still almost 50,000 missed diagnoses every year.For many women, that missed diagnosis comes from having dense breast tissue which prohibits clear results from a basic mammogram. Notre Dame professor Ryan Roeder is working to reduce the number of missed diagnoses in dense breast tissue by using gold nanoparticles. The nanoparticles can be injected into the breast and attach to indicators of cancer, like microcalcifications. Because gold is a heavy metal, in an X-ray or mammogram it will be seen clearly, even in dense tissue.Roeder’s project is far from the finish line, but optimism in this fight against breast cancer is high. With luck, partnerships and persistence, the best way to think pink may involve thinking gold.
