Researchers found that better access to healthcare can offset the natural decrease in mammogram use as a woman's life expectancy grows smaller. Women with limited life expectancy who live in areas with greater access to healthcare are more likely to be screened for mammograms.
Researchers have developed a new X-ray phase-contrast mammography technique that provides high-contrast images of breast tissue. This technique helps distinguish between different types of microcalcifications and can aid in assigning them to malignant lesions, enabling non-invasive detection of premalignant lesions.
A study found that women significantly overestimated radiation exposure from a single mammogram compared to other benchmarks. To address this, medical staff should inform patients about the low dose of radiation associated with mammography and provide objective facts to ensure informed decisions.

A new study found that computer-assisted detection (CAD) in mammograms improves the detection of noninvasive and early-stage invasive breast cancer, but also makes more mistakes. CAD was associated with higher rates of ductal carcinoma in situ (DCIS) diagnoses and increased diagnostic testing among women without breast cancer.

A new study published in JAMA Internal Medicine found that biennial mammography screening for women aged 50-74 does not increase the risk of advanced breast cancer, but rather reduces the risk of false-positive results. For women under 50 with extremely dense breasts, annual screening may be necessary to decrease the risk of advanced d...
A UCSF study of over 140,000 women aged 66-89 found that biennial screening led to fewer false positives and no increased risk of late-stage breast cancer. The study suggests life expectancy and co-existing illnesses should be considered when making cancer screening recommendations for older women.
