Multi-center study finds ultrasound screening finds more breast cancer; false positives may outweigh that benefit
Adding ultrasound exams to annual breast cancer screening can help physicians detect more cancers in women who have dense breasts and are at a higher risk of breast cancer, according to a three-year, multi-center trial appearing April 4 in the Journal of the American Medical Association. However, ultrasound has a downside: risks of false positive results and unnecessary biopsies that may outweigh the scans’ benefits.
Among the research institutions NCI funds across the United States, it currently designates 66 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.
