An Intelligent System for Predicting the Breast Cancer Threat Using Health Data Registry and Awareness: A Review

Breast cancer is the most frequently diagnosed life-threatening cancer in women worldwide, with about 2.1 million new cases every year according to World Health Organization. Breast cancer represents about 34.1% of all reported cancer cases in Omani females, with an average age of 34.7 and high mortality rates of 11 per 100,000 populations (GLOBOCAN 2018). The main cause of breast cancer is changing lifestyle and the risk factors such as age, family history, early mensural age, late menopause, obesity and contraceptive pills. Observations of recent literature informed that the prevalence of breast cancer is due to combination of risk factors. Occasionally unknown risk factors will also be the cause for the occurrence of breast cancer. Also, the impact of contribution of each of the risk factors in the cancer occurrence varies among the females. The aim of this research is to review the supervised machine learning techniques specifically Logistic Regression, Neural Networks, Decision Trees and Nearest Neighbors in order to predict the possibility of occurrence of breast cancer among the female population.
