A study found that 3-D mammography, although more expensive upfront, is a cost-effective screening method due to its higher true negative rates and lower false positive rates compared to digital mammography. The analysis of 46,483 screening episodes showed that DBT reduced cancer diagnosis-related costs in the following year.
A study published by Springer found that many women with high breast cancer risk are not receiving MRI scans, while those at lower risk are being screened too frequently. This highlights a missed opportunity to use technology that can help detect breast cancer early in high-risk groups.
Researchers found that contrast-enhanced digital mammography (CEDM) is comparable to breast MRI in evaluating residual breast cancer after neoadjuvant endocrine therapy or chemotherapy. CEDM may be a more accessible and cost-effective alternative to breast MRI, with fewer anxiety-provoking effects for patients.

However, colonoscopy screening rates remained unchanged despite eliminating out-of-pocket expenses under the ACA. The findings suggest that other barriers to colonoscopy access may still exist.
A large study analyzed over 5.6 million screening mammograms and found a gradual upward trend in cancer detection rates and positive predictive values with increasing age, but no clear evidence for age-based mammography cessation. The findings support guidelines encouraging individual patient decisions based on health status.
A study published in the American Journal of Roentgenology found that radiologists who compare prior mammograms with more than one image have better true-positive outcomes and fewer false-positives. This reduction in recall rates can lead to a decrease in anxiety, radiation exposure, biopsies, and healthcare costs for patients.

A comprehensive modeling study found that breast cancer screening with digital mammography poses only a small risk of radiation-induced breast cancer for most women. However, the research showed increased risk for women with large breasts or breast implants. The study suggests biennial screening from ages 50 to 74 may be the safest opt...
A systematic review of breast density studies found unreliable determinations and a significant risk of re-categorization. Supplemental diagnostic screenings for women with dense breasts may find additional cancers but also greatly increase false positive results, highlighting the need for more research on evaluation methods.
The USPSTF recommends regular mammography screening for women aged 50-74, with a recommended frequency of every two years. Women in their 40s should make an individual decision with their doctor about starting screening, considering factors like health history and preferences. The Task Force also notes that screening is less effective ...
A study published in JNCI Journal of the National Cancer Institute found that ultrasound sensitivity is comparable to mammography, but with a higher false-positive rate. The researchers suggest considering ultrasound as a supplemental test for women with dense breasts or those unable to tolerate MRI.
Women with a history of false-positive mammogram results may be at increased risk of developing breast cancer for up to 10 years after the initial false-positive result. A new study found that women who received a false-positive result had a 39% higher risk of subsequent breast cancer compared to those with true-negative results.
A new study suggests that breast density alone is not a significant risk factor for breast cancer in postmenopausal women. The study found no significant difference in breast density between breast cancer patients and control groups.

A large study found that high-grade DCIS detection rates increase with age, particularly among women over 65. The study suggests that standard DCIS therapy may not be effective in this age group and highlights the need for more research on the effectiveness of screening.
A study published in the Journal of the American College of Radiology describes a successful intervention to decrease anxiety related to mammography, increasing breast cancer screening rates. The study found that information about the logistics and outcomes of mammography reduced anxiety and improved understanding among participants.
A new study suggests that postmenopausal women may be safely screened every two years, while premenopausal women over 40 may benefit from annual mammograms to increase early detection. The research also highlights the importance of considering menopausal status rather than age when determining screening intervals.
The American Cancer Society recommends starting annual mammography screening at age 45 for average-risk women. Women between 40-44 can choose to begin annual screening. Clinical breast examination is no longer recommended due to lack of clear evidence on its effectiveness in detecting breast cancer.
