This study investigates the incidence and mortality of breast cancer globally using age-specific incidence and mortality rates from GLOBOCAN 2012 and national reports. In 2012, an estimated 1,671,149 new cases and 521,907 deaths from breast cancer were recorded worldwide. Breast cancer is the most common cancer among women, accounting for 25.1% of all cancers. Incidence rates are higher in developed countries, while relative mortality is greater in less developed countries. The study highlights the importance of early detection and treatment, particularly in less developed regions, and suggests that education for women is crucial for improving outcomes. The findings emphasize the need for better health policies and increased awareness of risk factors to control and prevent breast cancer.This study investigates the incidence and mortality of breast cancer globally using age-specific incidence and mortality rates from GLOBOCAN 2012 and national reports.
