Breast cancer risk is influenced by a combination of genetic, hormonal, and lifestyle factors. Women with a family history of breast cancer, especially with BRCA1 or BRCA2 gene mutations, face higher risk. Age also plays a role, as most cases occur after 50. Hormonal influences, such as early menstruation, late menopause, or hormone replacement therapy, can increase susceptibility. Lifestyle factors like obesity, lack of physical activity, smoking, and excessive alcohol intake further elevate risk. While some risks cannot be changed, adopting healthy habits, maintaining a balanced weight, and scheduling regular screenings can significantly reduce overall breast cancer risk.
