Most breast cysts do not heal on their own, and a few may do so under special circumstances. A malfunction in the development and degeneration of the breast can induce breast cysts, but this condition does not yet reach the category of disease. The size of the cyst is also related to whether a breast cyst can heal on its own: when it is less than 1 cm, it can slowly decrease and disappear over time, reaching self-healing; when it is larger in size, it usually cannot disappear on its own. If there are only cysts, the fluid inside the cysts can be extracted by aspiration, and after several times of aspiration, the cysts can gradually become smaller; some multiple breast cysts can also be treated by aspiration to achieve a curative effect. Breast cysts are benign diseases and the possibility of malignancy is low. Most of the patients with breast cysts do not need treatment and should be observed and followed up without too much anxiety and worry. It is best to regularly observe the changes in its shape and size during the disease, and if there are obvious changes, you should go to the hospital for consultation and treatment in time.
