Many women often experience breast swelling, tingling, and pins and needles discomfort and are very anxious about it. Through visits and physical examinations doctors often tell them it is because of lobular hyperplasia, but most women still have many questions and concerns. Mammary gland hyperplasia is an endocrine disorder hyperplasia, which occurs when the female breast grows and rejuvenates regularly with the menstrual cycle. When the metabolism of female hormones in the body is impaired, especially when the ratio of androgen and progesterone is imbalanced, the breast parenchyma becomes overly hyperplastic and incompletely rejuvenated, and the quality and quantity of female hormone receptors in some of the breast parenchyma components also vary, which can lead to breast discomfort, uneven texture, nodularity and other symptoms. Therefore, menstrual irregularities caused by fatigue, irregular life, depression, and abnormal metabolism can lead to increased discomfort of breast enlargement. It is more common to have transient breast swelling and pain during premenstruation, which does not require treatment. Irregular menstruation often leads to breast swelling and discomfort, and regulating menstruation often regulates the breasts. Mild breast enlargement is not associated with cancer, so there is no need to worry excessively or to take long-term medication. In addition, a healthy lifestyle is important, including a proper light diet, regular life and sleep, no anger, and a peaceful state of mind.
