The best time to have a mammogram should be 3-7 days after your period because mammography is the preferred screening method for diagnosing breast disease and is a reliable, non-invasive test with relatively little pain. It is characterized by the ability to detect lumps that cannot be touched by the doctor, especially in fatty breasts, and can be as high as 95% diagnostic. If you have breast pain, nodules or lumps, you need to have a mammogram in a timely manner. Mammograms should be performed between periods, ideally on the third to seventh day after your period. Do not apply any foundation, skin care products, deodorants or topical medications to your breasts before the exam, and you should wear clothes that are easy to put on and take off. Small lesions can easily be missed if examined during the premenstrual growth period. The breasts will swell and harden before the onset of menstruation, especially in patients with cystic hyperplasia, which can reveal lamellar or nodular breast tissue with pressure and swelling pain.
