Breast cancer is the most common cancer in women globally, accounting for 25.1% of all cancers. In 2012, there were 1,671,149 new cases and 521,907 deaths worldwide. Incidence rates vary widely, with higher rates in developed countries and lower rates in less developed ones. Mortality rates are also higher in less developed countries. Risk factors include long fertility, hormone use, obesity, physical inactivity, and alcohol consumption. Early detection and treatment are crucial, especially in less developed countries where awareness is low. Screening programs are more common in developed countries, but access is limited for immigrant and low-income women. In less privileged areas, patients often receive inadequate care, leading to higher mortality. The study highlights the need for improved health systems, better screening programs, and increased awareness of risk factors. National cancer registries are recommended to improve data collection and management. The study also notes that breast cancer incidence and mortality rates vary by region, with higher rates in certain areas and lower rates in others. Early detection and access to care are essential for reducing mortality. The study emphasizes the importance of developing effective strategies for prevention and control of breast cancer, particularly in less developed countries.Breast cancer is the most common cancer in women globally, accounting for 25.1% of all cancers.
