“…La ecografía mamaria usa el ultrasonido en la evaluación de las mamas, permitiendo caracterizar las lesiones sólidas y quísticas, y es particularmente útil en mujeres jóvenes o con mamas densas; además, es una técnica esencial para el diagnóstico y seguimiento de los tumores benignos de la mama [19]. No obstante, tampoco se ha llegado a un consenso general acerca de su uso como prueba alterna de tamización [7,20,21].…”

Introducción. El cáncer de mama es el cáncer que más afecta a las mujeres. Se estima que 1 en 8 mujeres desarrollarán cáncer de mama eventualmente. Una de las herramientas contra el cáncer de mama es crear estrategias de detección temprana de la enfermedad, y la mamografía ha demostrado ser de mucha utilidad. El objetivo del estudio fue determinar la frecuencia de la mamografía, ecografía, examen clínico y autoexamen mamario, y evaluar su uso como pruebas de tamización para cáncer de mama en una cohorte de pacientes atendidas en la Clínica del Prado en Medellín, Colombia. Metodología. Estudio descriptivo, transversal, efectuado a través de encuesta en 318 usuarias atendidas entre junio y diciembre de 2018. Se estimó la frecuencia de los diferentes métodos de tamización y se evaluaron las características sociodemográficas, antecedentes personales y antecedentes familiares. Adicionalmente, se buscó si había asociación significativa entre la práctica de la mamografía como prueba de tamización y las variables de estudio. Resultados. La media de la edad fue de 44,2 años. El método de tamización más usado fue el autoexamen (70,1%), en su mayoría mensual (76,7%), seguido por la mamografía (56%), en su mayoría ocasional (46%). El examen clínico de mama (ECM) se utilizó en el 45,9% de las pacientes, con una frecuencia anual en el 50% de ellas. Por último, la ecografía de mama se practicó en el 43,1% de las encuestadas, con una frecuencia en su mayoría ocasional (39,4%). Se realizó un análisis independiente para mujeres entre los 50 y 69 años, y aunque el 93,8% se habían realizado la mamografía, solo el 9,3% lo hizo bienal, como lo recomienda el Ministerio de Salud y Protección Social. No se hallaron diferencias estadísticamente significativas entre las variables de estudio y la realización de la mamografía como método de tamización. Conclusión. En la población estudiada, el autoexamen de mama es realizado por la mayoría de las mujeres con una frecuencia mensual. La frecuencia de la mamografía, el ECM y la ecografía de mama fue muy similar, y se esperaba encontrar un mayor porcentaje de mamografías realizadas como prueba de tamización. Se requiere fortalecer esta estrategia efectiva para la detección temprana de cáncer de mama, teniendo en consideración la situación particular de cada paciente, la efectividad y beneficio de la técnica, así como los costos asociados.

“…In clinical practice, to achieve the lower mobility of water molecules and shorter diffusion distances in these tissues, using a larger b-value (e.g., b = 500 s/mm 2 ) on DWI is suggested. Generally, the spread of water molecules on DW-MRI is restricted on malignant lesions with hypercellular areas or complex structures, presenting a high signal on DWI and accompanying low ADC value (108,109). Clinical practice shows (110) that the standard ADC value obtained by the traditional single-index DWI model is affected by the water molecule diffusion and microcirculation perfusion in the tissue and cannot well reflect the movement of water molecules in the tumor tissue.…”

Advances in radiation technology, such as intensity-modulated radiation therapy (IMRT), have largely enabled a biological dose escalation of the target volume (TV) and reduce the dose to adjacent tissues or organs at risk (OARs). However, the risk of radiation-induced injury increases as more radiation dose utilized during radiation therapy (RT), which predominantly limits further increases in TV dose distribution and reduces the local control rate. Thus, the accurate target delineation is crucial. Recently, technological improvements for precise target delineation have obtained more attention in the field of RT. The addition of functional imaging to RT can provide a more accurate anatomy of the tumor and normal tissues (such as location and size), along with biological information that aids to optimize the therapeutic index (TI) of RT. In this review, we discuss the application of some common MRI-based functional imaging techniques in clinical practice. In addition, we summarize the main challenges and prospects of these imaging technologies, expecting more inspiring developments and more productive research paths in the near future.

“…Genetic testing of B RCA mutation is one of the powerful tools for predicting breast cancer using various technologic advancements like digital radiography, MRI, ultrasound and tomosynthesi and thereby reduce mortalities and increase life expectancies [15,16]. The present study was aimed to assess the prevalence of all the risk factors associated with Breast Cancer, focusing more on reproductive factors which ha ve a direct impact on breast cancer development.…”

Breast Cancer is the second most common malignancy among Indian women accounting for 19-34%, next to cervical cancer. By early detection, understanding its pathogenesis and morphological features of the associated risk factors, one can prevent mortality against breast cancer. In India, high mortality is due to late diagnosis, poverty, fear and denial as majority of the patients present their condition in advanced or metastatic stage. The various risk factors associated with breast cancer include increasing age, geographical location, reproductive factors like early menarche or late menopause, family history, genetic mutations, nulliparity, avoiding breast-feeding, previous history of benign breast disease, exposure to radiations, use of exogenous hormones, obesity, dense breast tissue, sedentary lifestyle, smoking and. The aim of the present study was to assess the prevalence of associated risk factors of breast cancer in pre-menopausal and post-menopausal women of Hyderabad. A survey on 152 cancer women and 150 non-cancer women was done. A well structured questionnaire was employed to interview the subjects about their age, BMI, family history, reproductive health, diet and lifestyle. The data so collected was subjected to statistical analysis using chi square test. The results showed a positive correlation between breast cancer risk and age, increased BMI, family history, early marriage, late childbirth, consumption of exogenous hormones and breast-feeding (p<0.05). An awareness was also done through an illustrative brochure to educate the women about early detection of breast cancer, to implement healthy lifestyle interventions, importance of breast-feeding and poor impact of westernization of lifestyle. Thus, it was concluded from our study that there is a great impact of hormone-related factors and family history in the development of breast cancer.I. INTRODUCTION The mammary gland is a unique organ that undergoes extensive remodeling and differentiation even in adults. Hormonal changes in each menstrual cycle induce waves of proliferation in the mammary epithelium, whereas pregnancy leads to extensive ductal branching and alveogenesis [1]. Breast cancer starts when cells in the breast begin to grow out of control. These cells usually form a tumor that can often be seen on an x-ray or felt as a lump [2]. Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in females worldwide, accounting for 23% (1.38 million) of the total new cancer cases and 14% (458,400) of the total cancer deaths in 2008 [3]. Increasing trends in developing areas are often considered the result of the 'westernisation' of lifestyles, an ill-defined surrogate for changes in factors such as childbearing, dietary habits and exposure to exogenous oestrogen, towards a distribution closer in profile to that of women in industrialised countries. As a consequence of changing exposures to reproductive and nutrition-related determinants over time, women are at increasingly high risk of breast cance...
