Johns Hopkins researchers find that laser-light testing of breast tumor fiber patterns helps show whose cancer is spreading

  • Posted: November 2, 2012

Using advanced microscopes equipped with tissue-penetrating laser light, cancer imaging experts at Johns Hopkins have developed a promising, new way to accurately analyze the distinctive patterns of ultra-thin collagen fibers in breast tumor tissue samples and to help tell if the cancer has spread. The researchers say their crisscrossing optical images, made by shining a laser back and forth across a biopsied tissue sample a few millionths of a meter thick, can potentially be used with other tests to more accurately determine the need for lymph node biopsy and removal in women at risk of metastatic breast cancer.

NCI comprehensive cancer centers logoAmong the research institutions NCI funds across the United States, it currently designates 67 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
