Investigation of Breast Cancer Risk Factors in northern states of Sudan using Logistic Regression Analysis

Background: Breast cancer is the most common type of cancers and leading cause of death among women worldwide. In Sudan breast cancer is the most common type of cancer and its incidence has been rising for the past two decades.Objective: To investigate whether the breast risk factors of northern states (Northern and River Nile) are different from other states in Sudan.Methods: A case-control study was conducted in Radiation and Isotopes Centre Khartoum RICK targeting the breast cancer patients who came to get treatment or follow-up during 2010. A total of 60 breast cancer patients from northern states and 60 control breast cancer patients from other Sudan states were interviewed using purposively designed questionnaires. Logistic regression has been used for modeling the probability that a breast cancer could be developed as a function of risk factors.Results: This study showed that risk factors of breast cancer do not differ significantly between northern states (Northern and River Nile) and other Sudan states except the education level, are the patient alive, disease history and lactation.Conclusion: There is no difference between risk factors of breast cancer in all Sudanese states; all Sudanese women are exposed to breast cancer with matching risk factors.Key words: breast, risk factors, logistic regression
