A breast self-exam is a simple procedure that allows individuals to check their own breasts for any unusual changes. This can include lumps, swelling, or changes in shape or texture. It is recommended to perform these exams monthly, ideally a few days after the menstrual period ends, when breasts are less likely to be swollen or tender. Regular breast self-exams can help individuals become familiar with their own breast tissue, making it easier to notice any changes over time. While self-exams are important, they should not replace regular check-ups with a healthcare provider, such as a doctor or nurse, who can provide professional evaluations and screenings.
