Breast cancer screening is a process used to detect breast cancer in its early stages, often before symptoms appear. Common methods include mammograms, which are X-ray images of the breast, and clinical breast exams, where a healthcare provider checks for lumps or abnormalities. Regular screening can help identify cancer early, increasing the chances of successful treatment. Women are generally advised to begin screening at age 40, but recommendations may vary based on individual risk factors. Self-exams can also be part of a proactive approach, allowing individuals to become familiar with their breast tissue and report any changes to their healthcare provider.
