Because breast tissue composition partially predicts breast cancer risk, classification of mammography reports by breast tissue composition is important from both a scientific and clinical perspective. A method is presented for using the unstructured text of mammography reports to classify them into BI-RADS breast tissue composition categories. An algorithm that uses regular expressions to auto...

AdaBoost and Random Forests machine learning methods are compared using infrared hyperspectral images of breast cancer tissue with unbalanced class sizes. outperforms for small spectral numbers large imbalance.

The aetiology of breast cancer is multifactorial. While there are known genetic predispositions to the disease it is probable that environmental factors are also involved. Recent research has demonstrated a regionally specific distribution of aluminium in breast tissue mastectomies while other work has suggested mechanisms whereby breast tissue aluminium might contribute towards the aetiology o...

background: breast cancer is the most common malignancy in females worldwide. several etiological factors including environmental factors have been recognized for breast cancer. epstein barr virus as a viral etiological factor has been proposed. so far, several studies have investigated the relationship between development of breast cancer and epstein barr virus, but few have been done in iran....

Introduction: Contura is a balloon applicator that used to deliver intra cavity radiation for Partial Breast Irradiation (PBI) treatments. Contura with 4 peripheral lumens surrounding the central, for loading HDR sources from an after loader system can provide an asymmetric dose distribution and gives a more flexible shape of dose than earlier balloon applicators such as Mammo...

Introduction: Accelerated Partial Breast Irradiation (APBI) is an effective treatment for breast carcinomas because of its limited number of fractions. Strut-adjusted volume implant (SAVI) is a HDR brachytherapy applicator to deliver the prescription dose with good PTV coverage and acceptable dose to skin, chest wall and organ at risks. Acceptable clinical outcomes depend on a...

Background: Gynecomastia is a broadening of the glandular breast tissue and overlying skin in boys. The infection handle related with uneasiness, trouble, decreased quality life, an unsuitable body picture

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...

CONTEXT Exposure to sex steroids is associated with increased breast cancer risk, and adipokines, leptin and adiponectin have been implicated in cancer progression. However, it is not known whether sex steroids affect adipokine secretion in breast tissue. OBJECTIVE To elucidate the role of estrogen and tamoxifen on adipokine release in normal human breast tissue and breast cancer. SETTING A...
