A lump in the breast is also known as an accumulation of milk inside the breast, which may be accompanied by pain, increased surface skin temperature, acute mastitis, and so on. In the early stages, the milk is emptied as much as possible by means of massage or hot compresses. Breast massage is usually done by gradually squeezing and massaging from the periphery to the middle, that is, from the periphery of the ducts to the center of the ducts, to try to unblock them. You can also massage on both sides of the areola, that is, around the areola, through the clockwise or counterclockwise method, each massage for about 10 minutes, you can massage several times a day. Before and after the massage, use warm towels to warm the breasts as much as possible, so as to accelerate the local blood circulation, which is also very helpful for the recovery of the disease.
