Objectives: Most patients with breast lesions are usually anxious especially with the knowledge that breast cancer is associated with high rate of mortality and morbidity. The aim of this study is to ...evaluate the characteristics of breast lesion as depicted by mammography in women with symptomatic breast diseases. Methods: This was a prospective descriptive analytical study of women with symptomatic breast diseases who had mammography between January 2012 and December 2016 at our health facilities. Data sheet was developed to record the patients' biodata, indication for referral, and mammographic findings. Results: During the period of study, 166 females with symptomatic breast lesions had diagnostic mammography. The mean age was 49.29years ± 11.12. Sixty- five (39.2%) patients presented with breast lump, 54(32.5%) had breast pain, while 15 (9.0%) had nipple discharge. Seventy- five (45.2%) of the patients had no obvious lesion on mammogram, while 91(54.8%) had identifiable lesions. The masses were multiple in 9 (12.7%), diffused in 4 (5.6%) and solitary in 58 (81.7%). Six (3.6%) cases were found to have only calcifications. BI-RADS category 1 was the most prevalent constituting 75(45.2%). This was followed by BI-RADS categories 3 & 4, each constituted 30 (18.1%) cases. Conclusion: Breast diseases are common in our environment and this review had shown that most of these lesions were benign. Breast lumps and breast pains were the commonest indication for the mammograms and significant number of the patients had no demonstrable lesions on mammogram. BIRADS category 3 and 4 were more common
Este estudo transversal objetivou estimar a cobertura da mamografia no Estado de Goiás, Brasil, descrevendo sua oferta, demanda e variações para as diversas faixas etárias, tendo como unidades de ...observação 98 serviços de mamografia. Foram estimados as frequências de realização da mamografia por faixa etária e tipo de sistema de saúde, bem como o número de exames necessários para a cobertura de 70% e 100% da população-alvo.

This article presents a discussion about the knowledge of the female population about breast cancer, the means presented by the Unified Health System (Sistema Único de Saúde – SUS) that contribute to ...the diagnosis and adherence to the early identification process. It was developed through semi-structured interviews about personal satisfaction with health and its relationship with advancing age, knowledge about breast cancer, risk factors, prevention, and diagnostic imaging. It involved women living in the city of Belo Horizonte, Minas Gerais and the metropolitan region. A total of 440 interviews were carried out in 2019, focusing on women over 40 years old. Most women said they had already had a mammography, and a minority had undergone treatment for breast cancer. General data on the characterization of the women interviewed are presented, as well as the perception of care promoted by public policies for women's health care.
The validity of self-reported data for mammography differ by race. We assessed the effect of racial differences in the validity of age-adjusted, self-reported mammography use estimates from the ...Behavioral Risk Factor Surveillance System (BRFSS) from 1995 through 2006 to determine whether misclassification (inaccurate survey question response) may have obscured actual racial disparities.
We adjusted BRFSS mammography use data for age by using 2000 census estimates and for misclassification by using the following formula: (estimated prevalence - 1 + specificity) / (sensitivity + specificity - 1). We used values reported in the literature for the formula (sensitivity = 0.97 for both black and white women, specificity = 0.49 and 0.62, respectively, for black and white women).
After adjustment for misclassification, the percentage of women aged 40 years or older in 1995 who reported receiving a mammogram during the previous 2 years was 54% among white women and 41% among black women, compared with 70% among both white and black women after adjustment for age only. In 2006, the percentage after adjustment for misclassification was 65% among white women and 59% among black women compared with 77% among white women and 78% among black women after adjustment for age only.
Self-reported data overestimate mammography use - more so for black women than for white women. After adjustment for respondent misclassification, neither white women nor black women had attained the Healthy People 2010 objective (≥ 70%) by 2006, and a disparity between white and black women emerged.

We estimated the mammogram rates by age group and type of health service, as well as the number of tests required to cover 70% and 100% of the target population. We assessed the association between mammograms, geographical distribution of mammography machines, type of service, and age group. Full coverage estimates, considering 100% of women in the 40-69 and 50-69-year age brackets, were 61% and 66%, of which the Brazilian Unified National Health System provided 13% and 14%, respectively. To achieve 70% coverage, 43,424 additional mammograms would be needed. All the associations showed statistically significant differences (p < 0.001). We conclude that mammogram coverage is unevenly distributed in the State of Goiás and that fewer tests are performed than required.
Patients often present to surgeons with breast asymmetry of unknown etiology. Many patients are females in late adolescence and present complaining of a hypoplastic breast on the smaller side. ...However, the larger breast contains the abnormality.Lipomas of the breast are usually small, benign neoplasms which can be treated by simple excision.Diagnosis of these masses, however, can be difficult because of the normal fatty composition of the breast.Lipomas rarely causes breast asymmetry. We present ultrasonography,mammography and magnetic resonance imaging findings of a giant lipoma which causes asymmetry in 27 year old woman.
En esta última década se ha cuestionado el rol de la mamografía como método de screening para el cáncer de mama, relativizando su impacto en la disminución de la mortalidad por esta enfermedad.
Los ...ensayos clínicos randomizados se iniciaron en la década de los sesenta y los primeros metaanálisis mostraron el beneficio de la mamografía con una reducción de la mortalidad cercana al 30% en las mujeres sometidas a la intervención versus las que no, lo que justificaría la implementación de programas poblacionales masivos.
El énfasis de algunos científicos ha estado puesto en la crítica a los ensayos publicados, respecto a su falta de rigurosidad metodológica y a la revisión de estos, con estrictos estándares. Revisiones sistemáticas de la literatura y un metánalisis reciente han mostrado un menor beneficio de la mamografía y abierto la discusión sobre el costo beneficio de los programas de pesquisa precoz del cáncer de mama mediante mamografía.
Paralelamente se ha focalizado la atención en los daños asociados a los programas de screening, siendo el más importante el sobrediagnóstico y el subsecuente sobretratamiento.
Se revisa en este artículo los puntos más críticos de estas publicaciones, considerando el nuevo escenario que enfrentan médicos y pacientes frente a la decisión de incorporarse a un programa de screening mamográfico. Es imperativo que las mujeres estén debidamente informadas sobre la evidencia actual del beneficio y daños del screening.
Como contraparte, continúan los programas y en especial el seguimiento mamográfico a más largo plazo, que podría entregar nueva información, mejora la tecnología, el control de calidad de los procesos y conocimiento sobre la genética y biología molecular de los tumores, todos factores que podrían mejorar la pesquisa precoz del cáncer de mama.
During the last decade, the role of the mammography has been questioned as a screening method for breast cancer and its impact in mortality, reduction due to this illness. Randomized clinical essays began during the sixties and the first meta-analyses showed the benefits of a mammography in the decrease of mortality, nearly 30% in women under treatment, against the one who were not treated; therefore, this reduction justifies the implementation of large and massive programs for women.
Some scientists criticized the lack of methodology quality of the published essays, using high standards review. Current systematic reviews and a new meta-analysis have given less advantages for mammography, and have opened a discussion between the costs- benefits of programs focused on screening and early detection through mammography.
Parallel to this, it has been studied the damages associated with the screening programs being the over-diagnosis and the over-treatment the most important ones.
In this article, the most critical topics of the publications are revised, taking into consideration the new “scenario” that doctors and patients face, whether deciding to be part of a screening mammographic program. It is mandatory that women should know about the existing benefits and damages of the screening.
On the other side, programs continue to be developed specially the long-range tracing mammographic one, which can give new data, can improve technology and can control the high standards of these processes. Also allowed the acquisition of new concepts on genetics and molecular biology of tumors. All these factors could improve the screening of early breast cancer.
The purpose of this investigation was to compare and validate the performance of the SIERRA Monte Carlo simulation routines for the analysis of the scatter to primary ratio (SPR) in the mammography ...setting. Two Monte Carlo simulation methods were addressed, the direct method was a straightforward and geometrically accurate simulation procedure, and the convolution method uses idealized geometry (monoenergetic, normally incident delta function input to the scattering medium) to produce scatter point spread functions (PSFs). The PSFs were weighted by the x-ray spectrum of interest and convolved with the field of view to estimate SPR values. The SPR results of both Monte Carlo procedures were extensively compared to five published sources, including Monte-Carlo-derived and physically measured SPR assessments. The direct method demonstrated an overall agreement with the literature of 3.7% accuracy
(N=5),
and the convolution method demonstrated an average of 7.1% accuracy
(N=14).
The comparisons were made over a range of parameters which included field of view, phantom thickness, x-ray energy, and phantom composition. Limitations of the beam stop method were also discussed. The results suggest that the SIERRA Monte Carlo routines produce accurate SPR calculations and may be useful for a more comprehensive study of scatter in mammography.

Among many type of cancers in human body especially for woman in this modern world, the breast cancer is a key problem for their physical fitness. The early diagnosing of cancer for middle aged women ...in a major issue among us. In breast cancer detection using the images based on mammography, it's very difficult to detect exact cancer affected area due to the properties of the image. The Mammogram images occupy large size of file due to its high-resolution of graphic images. One can identify the cancer cells and the normal cells with contrast value, but the contrast difference is very thin. To identify and symbolize metastatic tumors in early stages and perform surveillance for most cancers recurrence, the volume of tumor can be measured by the use of Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) and useful characterization through Positron Emission Tomography (PET) imaging. In this article, breast cancer images are taken from medical repository and cancer affected regions are detected by region of interest and the cancer affected area is classified by the Susan technique and the results are tabulated. SUSAN corner detector is a good method which yield high quality features. To use in a real-time application, this is computationally demanding. In short amount of time, this can be used to build a feature detector. This Susan corner detector outperforms current feature detectors by a large margin.
