ABSTRACT Breast cancer continues to have a substantial impact on the health of women in the United States. It is the most commonly diagnosed cancer (excluding skin cancers) among women, with more than 210,000 new cases diagnosed in 2008 (the most recent year for which data are available). Incidence rates are highest among white women at 122.6 per 100,000, followed by blacks at 118 per 100,000, Hispanics at 92.8, Asian/Pacific Islanders at 87.9, and American Indian/Alaskan Natives at 65.6. Although deaths from breast cancer have been declining in recent years, it has remained the second leading cause of cancer deaths for women since the late 1980s with >40,000 deaths reported in 2008. Although white women are more likely to receive a diagnosis of breast cancer, black women are more likely to die from breast cancer than women of any other racial/ethnic group. In addition, studies have demonstrated that nonwhite minority women tend to have a more advanced stage of disease at the time of diagnosis. Breast cancer also occurs more often among women aged ≥50 years, those with first-degree family members with breast cancer, and those who have certain genetic mutations. Understanding who is at risk for breast cancer helps inform guidelines for who should get screened for breast cancer.

    ABSTRACT: Time delay after an abnormal screening mammogram may have a critical impact on tumor size, stage at diagnosis, treatment, prognosis, and survival of subsequent breast cancer. This study was undertaken to evaluate disparities between Latina and non-Hispanic white (NHW) women in time to definitive diagnosis of breast cancer after an abnormal screening mammogram, as well as factors contributing to such disparities. As part of the activities of the National Cancer Institute (NCI)-funded Redes En Acción research network, clinical records of 186 Latinas and 74 NHWs who received abnormal screening mammogram results were reviewed to determine the time to obtain a definitive diagnosis. Data was obtained from participating clinics in six U.S. cities and included demographics, clinical history, and mammogram characteristics. Kaplan-Meier estimates and Cox proportional hazards models were used to test differences in median time to definitive diagnosis by ethnicity after adjusting for clinic site, demographics, and clinical characteristics. Time-to-event analysis showed that Latinas took 2.2 times longer to reach 50% definitively diagnosed with breast cancer relative to NHWs, and three times longer to reach 80% diagnosed (p=0.001). Latinas’ median time to definitive diagnosis was 60 days compared to 27 for NHWs, a 59% gap in diagnosis rates (adjusted Hazard Ratio [aHR] = 1.59, 95% CI = 1.09, 2.31; p=0.015). BI-RADS-4/5 women’s diagnosis rate was more than twice that of BI-RADS-3 (aHR = 2.11, 95% CI = 1.18, 3.78; p=0.011). Disparities in time between receipt of abnormal screening result and definitive diagnosis adversely affect Latinas compared to NHWs, and remain significant after adjusting for demographic and clinical variables. With cancer now the leading cause of mortality among Latinos, a greater need exists for ethnically and culturally appropriate interventions like patient navigation to facilitate Latinas’ successful entry into, and progression through, the cancer care system.

    ABSTRACT: Recent reports have shown that the breast cancer incidence rate in the US stabilized after a sharp reduction in 2002 and 2003. It is important to continue monitoring breast cancer incidence rates according to age group, race/ethnicity, estrogen receptor (ER) status, and tumor stage. Age-standardized breast cancer incidence rates were calculated using data from the surveillance, epidemiology, and end results 18 registries from 2000 to 2009, for 677,774 female breast cancer patients aged 20 and above. Jointpoint regression models were used to fit a series of joined straight lines on a log scale to annual age-standardized rates. The incidence rates of all breast cancer significantly increased for non-Hispanic blacks from 2005 to 2009 (annual percentage change, APC = 2.0 %, p = 0.01) and Asian/Pacific Islanders from 2000 to 2009 (APC = 1.2 %, p = 0.02). Since 2004, incidence rates in women aged 40–49 years significantly increased for most racial/ethnic groups (overall APC = 1.1 %, p = 0.001). The incidence rate of carcinoma in situ significantly increased in all racial/ethnic groups, with an APC range from 2.3 to 3.0 % (p p = 0.004) and Asians (APC = 1.2 %, p = 0.03). ER-positive breast cancer significantly increased in almost all age/race sub-groups after 2005 (APC by race: non-Hispanic whites 1.5 %, non-Hispanic blacks 4.3 %, Asian/Pacific Islanders 1.7 %, and Hispanics 1.8 %; all p values Pacific Islanders—1.5 %, and Hispanics—4.3 %; all p values Pacific Islanders. Further studies are warranted to examine possible reasons for these changes, such as changes in mammography screening methods and risk factors prevalence.

    ABSTRACT: Screening mammography is a cornerstone of preventive health care for adult women in the United States. As rates of screening mammography have declined and plateaued in the past decade, access to services remains a concern. In 2011, we repeated a survey of mammography facilities initially surveyed in 2008 in six states. The availability of digital mammography increased and appointment wait times generally improved between the two survey periods, but more facilities required payment upfront. Provisions of the federal healthcare reform law that eliminate cost sharing for selected preventive health services may improve access to screening mammography and prevent further declines in the rate of breast cancer screening.
