introduction accurate estimation of the skin-absorbed dose in external radiation therapy is essential to estimating the probability of secondary carcinogenesis induction materials and methods electron contamination in prostate radiotherapy was investigated using the monte carlo (mc) code calculation. in addition, field size dependence of the skin dose was assessed. excess cancer risk induced by...
cancer is uncontrolled and unrestricted growth of malignant cells in the body. it is a multifactorial disease which either heredity or environmental factors (such as nutrition, physical inactivity, alcohol, obesity, exposure to sun, environmental pollutants, infections) contribute to the incidence of cancer. in recent years, several lines of research have focused on obesity as a potent risk fac...
Background: Prediction of breast cancer risk and identifying women who are at high risk of breast cancer, would be a great help for planning and conducting screening programs. The aim of this study was to estimate the 5-year breast cancer risk among women in Isfahan. Methods: This cross-sectional study was conducted on 9674 women aged 35-69 years who referred to the Breast Cancer Screening Cen...
intercellular adhesion molecule-1 (icam-1) lys469glu (k469e) polymorphism and gly 241arg (g241r) polymorphism might play important roles in cancer development and progression. however, the results of previous studies are inconsistent. the aim of this study was to evaluate the association between icam-1 k469e and g241r polymorphisms and the risk of cancer by meta-analysis.a comprehensive literat...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
epidemiological evidence shows that cancer and diabetes are major causes of death in the world. type2 diabetes increases the risk of cancer-specific mortality. this review relates diabetic therapies, diabetes and cancer.all published papers in this field were searched, looking into such databases as science direct, isi web of knowledge, pubmed and scopus.in cancer patients, metformin improves p...
background: the etiology of breast cancer and our understanding on the carcinogenicity of different risk factors is impotant for control programms. objective: we investigated the expression of estrogen and progesterone receptors (er, pr), and human epithelial receptor 2 (her2) overexpression and its associations, with environmental risk factors among breast cancer patients. methods: we classif...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
introduction: gail model is one of the most important models for the evaluation of breast cancer risk between us white females. according to genetic diversity, there is a possibility of affecting the efficiency of the gail model in risk assessment of breast cancer among iranian populations. in this study, the gail model efficiency in specifying the risk of breast cancer in iranian population wa...
