If there is painful swelling and hard lumps in the breasts after abortion, it is recommended to go to the hospital in time for appropriate examination, such as color ultrasound examination of the breast or mammogram, to rule out the possibility of other organic lesions. If there is no organic lesion, it may be related to the oral short-acting contraceptive pill taken after abortion. Short-acting contraceptive pills are a combination of estrogen and progestin, and when taken after abortion, they will often repair the endometrium as soon as possible, shorten the time of vaginal bleeding, and reduce the chance of infection, and will have a good contraceptive effect. Therefore, after abortion, women are recommended to take short-acting contraceptive pills, but short-acting contraceptive pills also have their side effects, such as localized breast pain. If there is localized breast pain after abortion, excluding organic lesions, it may be related to taking short-acting contraceptive pills, but usually the symptoms will disappear after stopping the pills.
