Women are encouraged to perform breast self-examinations monthly, ideally a few days after their menstrual period ends, when the breasts are least likely to be swollen or tender. Clinical breast examinations should be part of annual gynecological check-ups, especially for women over the age of 40 or those with a family history of breast cancer. Mammograms are typically recommended annually or biennially starting at age 40, though this may vary based on individual risk factors.
