If breast lumps appear, breast milk should be sucked out in time to make the lumps subside quickly. It is a common phenomenon that breast milk rises after weaning, mainly due to breast swelling and pain, some of which may be accompanied by breast lumps. If there is a hard lump, it is recommended to use a breast pump to discharge the milk and massage the breasts gently, rubbing away the hard lump, which will help the hard lump to subside quickly. In addition, women should also pay attention to avoid violent pressure on the breast, so as not to induce acute mastitis. If the lump is accompanied by redness of the skin, increase in temperature or even fever, it is considered as acute mastitis and should be seen by the mammography department and other related departments in a timely manner, and if necessary, antibacterial medication should be given. It is recommended that women should pay attention to rest and avoid straining during weaning; drink less soup and water, eat a light diet and avoid grease; relax and ensure the cleanliness and hygiene of the breasts, etc., all of which will help to reduce the rise of milk.
