Breast cancer is the second most common cancer in American women, and the second leading cause of cancer deaths in women, according to the American Cancer Society. It claimed the lives of more than 41,000 women in the United States in 2019 and changed the lives of 3.5 million breast cancer survivors.
At the University of Notre Dame, a research team led by Thomas O’Sullivan, assistant professor of electrical engineering and an expert in biomedical optical sensing and imaging, hopes to revolutionize breast cancer treatment by developing the first “smart” breast marker clip.
“As researchers, we were seeking a way to provide the most relevant and timely information possible to indicate that a tumor or metastasis was either responding to or becoming resistant to treatment,” says O’Sullivan. “Since marker clips were already routinely introduced in breast tumors, we began to envision ways to create ‘smart’ versions of these markers that could provide that information in near real-time so they could be used to optimize treatment at the earliest possible opportunity.”
About the size of a sesame seed, breast marker clips are commonly placed in the body during a biopsy, where breast tissue was removed. The biologically safe clip “marks” the biopsy area and can be seen on post-biopsy mammograms to more quickly identify the affected tissue.
