A new study in JAMA Internal Medicine found that when women controlled the level of breast compression during mammography, image quality was not compromised. A French team studied 548 women, 275 of whom had mammography with self compression and 273 had standard mammography. Self-reported pain was lower in those with self compression, who only had an average three millimeter difference in compression compared to those with the standard test. In a Reuters Health report of the study, MSK’s Dr. Deborah Korenstein said that when women control compression, they may have more comfortable tests and be less likely to avoid mammograms in the future.
