Breast cancer is a malignant tumor and the most common cancer among American women that starts from cells of the breast. The growth of the size of data exceeds the ability of humans to analyze the data. So we need some intelligent machines that can analyze datasets intelligently for us. We propose a Multi Nominal Logit Model to evaluate correlation between risk factors of breast tumor. Our ...

PURPOSE The purpose of this study was to evaluate the prognostic effect of early posttransplant lymphocyte recovery in patients with advanced breast cancer receiving high-dose chemotherapy with autologous hematopoietic progenitor cell transplantation. EXPERIMENTAL DESIGN We analyzed the effect of the absolute lymphocyte count on day +15 posttransplant on freedom from relapse and overall survi...

the present research is a field study in order to investigate scale and ways of doing breast self examination (bse). 270 nurses employed by the medical sciences university’s hospitals related to the ministry of health, and medical education in city of tehran are selected and involved in research on the basis of simple random sampling. the data collection tool was a protrayed questionnaire which...

background: the aim of this study is to evaluate the association between different treatments and survival time of breast cancer patients using either standard cox model or stratified cox model. methods: the study was conducted on 15830 women diagnosed with breast cancer in british columbia, canada.  they were divided into eight groups according to patients’ ages and stage of disease either cox...

Obesity has been consistently associated with an increased risk of postmenopausal breast cancer in population-based studies. Conversely, obesity in such studies has been inversely associated with premenopausal breast cancer risk. In a report of data from two large chemoprevention trials, both of which enrolled women at a high risk of breast cancer, obesity was associated with only a modest, non...

The incidence of breast cancer in Korea has been increasing in recent years, such that it is now the most common female cancer. Breast cancer in Korea is characterized by an earlier age of onset than in Western countries, suggesting that it would be related with genetic background. We assayed germline mutations in the BRCA genes to evaluate their genetic pathology in Korean breast cancer patien...

Breast cancer is the commonest malignancy diagnosed inwomen worldwide and accounts for over 30% of all cancers diagnosed in women in the United Kingdom. The average lifetime risk of developing breast cancer for women in the United Kingdom and United States is estimated to be 12%, although this may be an overestimate, as it is not clear what age this assumes a woman lives to and whether full adj...

OBJECTIVE Antiestrogens reduce the risk of estrogen receptor-positive (ER+) but not ER-negative (ER-) breast cancer. Women at high risk of ER+ cancer would be the most likely to benefit from these treatments, but the best approach to predicting ER+ cancer is uncertain. METHODS We prospectively assessed putative risk factors for breast cancer and archived serum at -190 degrees C from a communi...

Background: MDM2 (Murine Double Minute2) is an oncoprotein that inhibits the P53 activity. Overexpression of MDM2 gene has been reported in several human tumors. In the present study, we aimed to evaluate the impact of 40-bp insertion/deletion (ins/del) polymorphism on the promoter of MDM2 and susceptibility to breast cancer in a sample of Iranian population. Methods: This case-control study wa...
