BACKGROUND:Massachusetts law requires all residents to maintain a minimum level of health insurance, and rates of uninsurance in that state decreased from 6.4% in 2006 to 1.9% in 2010. The authors of this report assessed whether health insurance expansion was associated with use of mammography and earlier stage at breast cancer diagnosis.
METHODS:By using a prereform/postreform design with a concurrent...
BACKGROUND:In November 2009, the US Preventive Service Task Force (USPSTF) published updated breast cancer screening guidelines. This marked a change from the 2002 recommendations and a significant divergence from the American Cancer Society (ACS) guidelines. In the current study, the potential effect of using the revised 2009 USPSTF guidelines on patient disease stage and survival were evaluated...
BACKGROUNDAfter the introduction of a mammography screening program, the incidence of late‐stage breast cancer is expected to decrease. The objective of the current study was to evaluate variations in the total incidence of breast cancer and in the incidence of breast cancers with a pathologic tumor (pT) classification of pT2 through pT4 after the introduction of mammography screening in 6 Italian...
BACKGROUNDUS breast cancer mortality is declining, but thousands of women still die each year.
METHODSTwo established simulation models examine 6 strategies that include increased screening and/or treatment or elimination of obesity versus continuation of current patterns. The models use common national data on incidence and obesity prevalence, competing causes of death, mammography characteristics,...
BACKGROUNDIn November 2009, the US Preventive Services Task Force (USPSTF) issued new recommendations regarding mammography screening. The Task Force recommended against routine screening for women ages 40 to 49 years and recommended biennial screening for women ages 50 to74 years. The recommendations met great controversy in mass media and medical literature; whether they have had an impact on screening...
BACKGROUNDPrimary care physician (PCP) services may have an impact on breast cancer mortality and incidence, possibly through greater use of screening mammography.
METHODSThe authors conducted a retrospective, 1:1 matching case‐control study using the Surveillance, Epidemiology, and End Results (SEER)‐Medicare–linked database to examine use of PCP services and their association with breast cancer...
BACKGROUNDThe Norwegian Breast Cancer Screening Program started in 1996. To the authors' knowledge, this is the first report using individual‐based data on invitation and participation to analyze breast cancer mortality among screened and nonscreened women in the program.
METHODSInformation on dates of invitation, attendance, breast cancer diagnosis, emigration, death, and cause of death was linked...
BACKGROUNDAnnual surveillance mammography is recommended after a diagnosis of breast cancer. Previous studies have suggested that surveillance mammography varies by demographics and initial tumor characteristics, which are related to an individual's access to health care. The Military Health System of the Department of Defense provides beneficiaries with equal access health care and thus offers an...
BACKGROUNDRates of screening mammography have plateaued, and the number of mammography facilities has declined in the past decade. The objective of this study was to assess changes over time and geographic disparities in the availability of mammography services.
METHODSUsing information from the US Food and Drug Administration and the US Census, county‐level mammography capacity was defined as the...
BACKGROUNDBiennial screening mammography retains most of the benefits of annual breast cancer screening with reduced harms. Whether screening guidelines based on race/ethnicity and age would be more effective than age‐based guidelines is unknown.
METHODSMammography data from the Breast Cancer Surveillance Consortium were linked to pathology and tumor databases. The authors identified women aged 40...
BACKGROUNDSome false‐positive results are inevitable in mammographic screening, but the impact of false‐positive findings on the program and the participants is a disadvantage of screening. The objective of the current study was to estimate the cumulative risk of a false‐positive result over 10 biennial screening examinations and the cumulative risk of undergoing an invasive procedure with a benign...
