Cystic breast nodules, also known as cystic breast hyperplasia, is one of the most common and frequent diseases in women, most commonly seen in women between the ages of 20 and 45. Breast cystic nodules are a proliferative disease of the breast. Generally speaking, breast cystic nodules are benign diseases, but there is still a possibility of malignant transformation. Some cystic breast nodules are associated with the menstrual cycle, and after menstruation, the nodules shrink and become softer; such breast nodules may be caused by breast hyperplasia. Some patients may also have had milk accumulation during breastfeeding, and the cystic nodules appear after a longer course of the disease when the milk accumulation improves. Surgical removal of cystic breast nodules can eliminate the lesions and achieve the desired results. Patients need to consult a doctor in time and choose the appropriate treatment plan under the guidance of a professional doctor, which is conducive to the rapid alleviation of the condition. Patients should avoid squeezing and scratching the breasts in order to avoid irritating the lesions.
