introduction:there is considerable amount of controversy about the long term effects of multiparity and duration of breast-feeding on maternal bone mineral density after menopause. this study was conducted to determine whether multiple pregnancy and prolonged duration of breast-feeding are independent predictors of low bone mass in post-menopausal kurdish women. methods: in a retrospective stud...

background: we conducted our study on 1110 patients with breast masses in order to investigate different aspects of power doppler sonography (pds) for differentiating between benign and malignant breast lesions and their prognostication. materials and methods: this study was conducted on the women who were referred to the sonography units of university hospitals for breast sonography and had a ...

background: mammographic density has been recognized as a risk factor for breast cancer,  but  the  association between  potential  effective factors and  mammographic density has not been fully studied in asian women. we conducted a study to investigate the association of mammographic breast   density with several menstrual and reproductive characteristics. m ethods: screening  mammography  wa...

results in patients with high breast densities, malignant cases (61.2%) were significantly more in comparison to patients with low breast densities (37.3%) (p= 0.007, or=2.66 95% ci=1.29-5.49). after adjusting for age, density was associated with malignancy in age groups <46 years (p=0.007), and 46-60 years (p=0.024) but not in age group >60yrs (p=0.559). adjusting for menopausal status, densit...

phyllodes tumors account for less than 1% of breast tumors in women. giant phyllodes tumors are larger than 10 cm in diameter. a 40-year-old lady presented with a left breast lump that was present for two years. she underwent a simple mastectomy. the tumor was 30×26×21 cm in size, weighed 15 kg and had a density of 0.915 gr/cm3. we believe this patient had the third largest breast phyllodes tum...

in order to evaluate the possible correlation between the tree density and the human population density, the forested area in nav asalem district located in guilan province was selected. the descriptors of tree number and basal area per hectare as well as the stand density index were used to determine the tree density, which was conducted from a 2014 forest inventory including 62 cluster (558 p...
