​Breast self-examination (BSE) is a personal and proactive way to monitor your breast health. By regularly checking your breasts for any changes, such as lumps, swelling, or unusual shape, you can become familiar with what is normal for you. It’s recommended perform BSE monthly, ideally a few days after your menstrual period. If you notice any changes, consult a healthcare professional for further evaluation. It's a valuable tool for breast awareness and can help you identify potential abnormalities early, though it's not a replacement for regular clinical breast exams or mammograms
