why breast cancer occurs

Breast cancer can indeed be perplexing because it emerges from a combination of multiple factors, and it’s understandable to feel puzzled especially when someone like your mom seemed to lead a healthy lifestyle. There isn’t a single cause for breast cancer; rather, it’s typically due to an interplay of genetic, hormonal, and environmental influences. Family history isn’t always a contributor, as about 85% of breast cancers occur in women with no family history of the disease. Genetic mutations, like BRCA1 and BRCA2, are well recognized risk factors, but they are not the only ones. Hormones play a pivotal role; prolonged exposure to estrogen, either through early menstruation, late menopause, or hormone replacement therapy, can increase risk. Environmental factors are noted too, although their role is less clear deninite, with substances like certain chemicals potentially acting as endocrine disruptors. In terms of lifestyle, regular physical activity, maintaining a healthy weight, and minimizing alcohol consumption are known ways to reduce risk. Smoking has been indirectly linked as it can influence the general environment of risk factors in the body over time. When considering your own situation, a talk with a healthcare provider about genetic counseling or screening might be beneficial, as they can evaluate whether genetic testing is suitable. Mammograms and self-exams are valuable parts of surveillance, especially if you’re approaching the age where screening typically begins or if you have concerns. Generally, be proactive by adhering to a healthy lifestyle; while it doesn’t eliminate the risk entirely, it can help manage and potentially lower it.
