Normal breast development, if inflammation occurs, resulting in hyperplasia of the breast, it is possible to develop hard lumps, which will tend to calm down as soon as the inflammation is eliminated. If the inflammation is not relieved for a long time, it will cause serious hyperplasia of the breast ducts, which may evolve into breast cancer in 1/3 of patients clinically. A normal hard lump in the breast will not be very painful and is on both sides of the breast. Generally, attention is paid to inflammation and fire, and it will be eliminated in about three weeks. If there is obvious swelling and pain, especially around the areola, and there is a nodular sensation throughout the breast, and the pain is worse when touched, it is possible that the lump is causing plasmacytic mastitis. It is caused by the dilatation of the breast ducts and the surrounding inflammation, which in severe cases may secrete a foul-smelling fluid. In the middle of the disease, breast fibroids may appear, and in the later stages of the disease, breast cancer may appear. Fibroids can be removed by puncture, and current medical technology allows for safe and painless removal at once. Before confirming the diagnosis, it is best to have a mammogram to determine the location and size of the lump, and then determine whether the lump is benign or not, and finally take the correct treatment and treatment advice. If a lump appears in the breast during development, it needs attention. If the lump is difficult to be removed for a long time, it needs to be checked in time, otherwise the condition may be delayed.
