U.K. study strengthens case for breast MR screening
A multicenter study published online May 16 by The Lancet has shown that a combination of MRI and mammography offers the best means of detecting breast cancer in women with a high genetic risk for the disease.
A multicenter study published online May 16 by The Lancet has shown that a combination of MRI and mammography offers the best means of detecting breast cancer in women with a high genetic risk for the disease.
The investigators found MRI significantly more sensitive than mammography (77% versus 40%) in detecting breast cancers across the group of 649 women. Combining the results increased the sensitivity to 94%. MRI proved especially effective in BRCA1 mutation carriers, in whom it detected all tumors. Both techniques were needed to spot all cancers in women carrying BRCA2 mutations.
Commenting on the study, Dr. Ellen Warner, a medical oncologist at Toronto-Sunnybrook Regional Cancer Centre, said that mammography may one day be abandoned for high-risk women.
What a New Mammography Study Reveals About BMI, Race, Ethnicity and Advanced Breast Cancer Risk
December 8th 2023In a new study examining population attributable risk proportions (PARPs) based on data from over three million screening mammography exams, researchers found that postmenopausal Black women had the highest BMI-related PARP and premenopausal Asian and Pacific Islander women had the highest breast density-related PARP for advanced breast cancer.
Study: Contrast-Enhanced Mammography Changes Surgical Plan in 22.5 Percent of Breast Cancer Cases
December 7th 2023Contrast-enhanced mammography detected additional lesions in 43 percent of patients and led to additional biopsies in 18.2 percent of patients, over half of whom had malignant lesions, according to a study of over 500 women presented at the recent Radiological Society of North America (RSNA) conference.
