TL;DR: Regular mammography among women >or= 80 years of age was associated with earlier disease stage, although improved survival remains difficult to demonstrate.
Abstract: Purpose Screening mammography guidelines for patients age 80 years and older are variable. We determined the effect of mammography use on stage at breast cancer diagnosis and survival among women of this age range. Patients and Methods We used the linked Surveillance, Epidemiology, and End Results–Medicare database to evaluate 12,358 women ≥ 80 years of age diagnosed with breast cancer between 1996 and 2002. Patients were grouped according to number of mammograms during the 60 months before diagnosis: nonusers (0 mammograms), irregular users (one to two mammograms), and regular users (three or more mammograms). Effects of mammography on disease stage (I to IIa v IIb to IV) and survival were determined by logistic regression and Cox proportional hazards analyses. Results Percentages of women with nonuse, irregular use, and regular use of mammography during the 5 years preceding diagnosis were 49%, 29%, and 22%, respectively. On multivariate analysis, patients were 0.37 times less likely to present with lat...

TL;DR: In this paper, a method and system for generating tomographic mammography data and processing the data using a computer aided detection and diagnosis (CAD) algorithm is presented, where the acquired data may be processed in parallel by the CAD algorithm such that information derived from one processing path may be used to enhance or alter the processing of data in a parallel processing path.
Abstract: The present technique provides a method and system for generating tomographic mammography data and processing the data using a computer aided detection and diagnosis (CAD) algorithm. The CAD algorithm may perform various types of analysis, including segmentation, feature extraction, and feature classification. The acquired data may be processed in parallel by the CAD algorithm such that information derived from one processing path may be used to enhance or alter the processing of data in a parallel processing path. The processed data may be used to provide an enhanced mammographic image with features of interest marked for inspection by a radiologist. The features of interest may also be classified to aid the inspection by the radiologist.

TL;DR: Clinicians should discuss breast density as 1 of several important breast cancer risk factors, consider the potential harms of adjunctive screening, and arrive at a shared decision consistent with each woman's preferences and values, according to current screening mammography performance.

TL;DR: The results show very low rates of breast cancer screening in the Kingdom of Saudi Arabia, a country with free health services, and calls for educational campaigns to improve breast cancer screenings.
Abstract: Introduction Mammography ensures early diagnosis and a better chance for treatment and recovery from breast cancer. We conducted a national survey to investigate knowledge and practices of breast cancer screening among Saudi women aged 50 years or older in order to inform the breast cancer national health programs. Materials and methods The Saudi Health Interview Survey is a national multistage survey of individuals aged 15 years or older. The survey included questions on socio-demographic characteristics, tobacco consumption, diet, physical activity, health-care utilization, different health-related behaviors, and self-reported chronic conditions. Female respondents were asked about knowledge and practices of self and clinical breast exams, as well as mammography. Results Between April and June 2013, a total of 10,735 participants completed the survey. Among respondents, 1,135 were women aged 50 years or older and were included in this analysis. About 89% of women reported not having a clinical breast exam in the past year, and 92% reported never having a mammogram. Women living in Al Sharqia had the highest rate of mammography use. Women who were educated, those who had received a routine medical exam within the last two years, and those who were diagnosed with hypertension were more likely to have had a mammogram in the past two years. Discussion Our results show very low rates of breast cancer screening in the Kingdom of Saudi Arabia, a country with free health services. This calls for educational campaigns to improve breast cancer screening. Addressing the barriers for breast cancer screening is a public health imperative.

TL;DR: Breast cancer management appears compromised in elderly patients (older than 65 years of age) and frequency of mammography screening is significantly less in elderly women older than 65 age, which may further reduce the opportunity to detect potentially curable cancers.
Abstract: Objective The suggestion that breast cancer management is compromised in elderly patients had prompted our review of the results of policies regarding screening and early detection of breast cancer and the adequacy of primary treatment in older women (<65 years of age) compared to younger women (40 to 64 years of age). Background Data Although breast cancer in elderly patients is considered biologically less aggressive than similar staged cancer in younger counterparts, outcome still is a matter of stage and adequate treatment of primary cancer. For many reasons, physicians appear reluctant to treat elderly patients according to the same standards used for younger patients. There is even government-mandated alterations in early detection programs. Thus, since 1993, Medicare has mandated screening mammography on a biennial basis for women older than 65 years of age compared to the current accepted standard of yearly mammograms for women older than 50 years of age. Using State Health Department and tumor registry data, the authors reviewed screening practice and management of elderly patients with primary breast cancer to determine the effects of age on screening, detection policies (as reflected in stage at diagnosis), treatment strategies, and outcome. Methods Data were analyzed from 5962 patients with breast cancer recorded in the state-wide Tumor Registry of the Hospital Association of Rhode Island between 1987 and 1995. The focus of the data collection was nine institutions with established tumor registries using AJCC classified tumor data. Additional data were provided by the State Health Department on screening mammography practice in 2536 women during the years 1987, 1989, and 1995. Results The frequency of mammographic screening for all averaged 40% in 1987, 52% in 1987, and 63% in 1995. In the 65-year-old and older patients, the frequency of screening was 34% in 1987, 45% in 1989, and 48% in 1995, whereas in the 40- to 49-year-old age group, the frequency of mammography was 47% in 1987, 61% in 1989, and 74% in 1995 (p < 0.001). There was a lower detection rate of preinvasive cancer in the 65-year-old and older patients, 8.8% versus 13.7% in patients within the 40- to 64-year-old age group (p < 0.001). There was a higher percentage of treatment by limited surgery among elderly patients with highly curable Stage IA and IB cancer with 26.6% having lumpectomy alone versus 9.4% in the younger patients. Five-year survival in that group was significantly worse (63%) than in patients treated by mastectomy (80%) or lumpectomy with axillary dissection and radiation (95%, p < 0.001). A similar effect was seen in patients with Stage II cancer. Conclusions Breast cancer management appears compromised in elderly patients (older than 65 years of age). Frequency of mammography screening is significantly less in elderly women older than 65 years of age. Early detection of preinvasive (curative cancers) is significantly less than in younger patients. The recent requirement by Medicare of mammography every other year may further reduce the opportunity to detect potentially curable cancers. Approximately 20% of patients had inferior treatment of favorable stage early primary cancer with worsened survival. Detection and treatment strategy changes are needed to remedy these deficiencies.
