aim : this study aims to investigate some clinical and pathologic factors associated with the prognosis of patients with colon and rectum cancers separately. background : colorectal cancer is the most common cancer of the digestive system and also the fourth cause of cancer-related deaths around the world. different studies indicate that survival of patients with colorectal cancer has improved ...

background: previous studies indicate a high incidence of digestive cancers along southern parts of caspian sea including ma­zandaran province. the present study was conducted to further investigate time to occurrence, age distribution and pos­sible risks associated with the incidence time of digestive cancers in the above regions. methods: for this purpose the data of digestive cancer incidenc...

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...

Background: Breast cancer is one of the most important malignancies in both developed and developing countries. Objectives: To reduce the burden of this disease, the prediction of individuals at risk and implementation of efficient preventive interventions can be effective. The present study was aimed at investigating five-year and lifetime risks of the breast cancer in a rural community in Za...

Background: The aim of this study was to estimate the cancer risks and mortalities of different types induced by routine examinations of digital radiography for one year in Mazandaran province, Iran. Materials and methods: Radiation parameters and calculated entrance skin dose (ESD) values of 13 digital radiographic examinations were collected from 2340 patients at 18 high-patient-load radiogra...

Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...
