Imperfect correlation of mammographic and clinical breast tissue density.
BACKGROUND Clinicians determine degree of mammographic density based on tissue firmness on breast examination. The study aimed to compare breast density in mammography and clinical breast examination. MATERIALS AND METHODS Six-hundred sixty three women 40 years of age or older were studied. The breast exam density was graded from 1 to 4 by two expert surgeons and the mammographic parenchymal ...
متن کاملInvestigating the Factors Affecting the Mammographic Density of Breast Tissue in Patients Referred to the Breast Cancer Research Center, Iran
Introduction: Of the factors leading to false negative results in mammography is breast tissue density, and by increasing the density of breast tissue in mammography, the mammography sensitivity decreases. On the other hand, increasing the breast tissue density leads to increased risk of breast cancer. Various factors such as inheritance, genetics, hormonal and reproductive factors, and nutriti...

متن کاملRelationship of mammographic density and gene expression: analysis of normal breast tissue surrounding breast cancer.
PURPOSE Previous studies of breast tissue gene expression have shown that the extratumoral microenvironment has substantial variability across individuals, some of which can be attributed to epidemiologic factors. To evaluate how mammographic density and breast tissue composition relate to extratumoral microenvironment gene expression, we used data on 121 patients with breast cancer from the po...
متن کاملMammographic density and breast cancer risk: evaluation of a novel method of measuring breast tissue volumes.
BACKGROUND Mammographic density has been found to be strongly associated with risk of breast cancer. We have assessed a novel method of assessing breast tissue that is fully automated, does not require an observer, and measures the volume, rather than the projected area, of the relevant tissues in digitized screen-film mammogram. METHODS Sixteen mammography machines in seven locations in Toro...
