Breast hyperplasia nodule is a common clinical breast disease, which is usually caused by endocrine disorders, increased estrogen or decreased progesterone. 1. Endocrine disorders: the imbalance of estrogen and progesterone stimulates the mammary glands, resulting in excessive mammary gland hyperplasia but incomplete recovery, which leads to breast hyperplasia, which can be treated with medicines such as Manfrotto and Eosin under the guidance of a doctor. 2. Excessive estrogen secretion: patients who often stay up late or do not sleep well may suffer from endocrine disorders leading to excessive estrogen secretion, which may even increase the risk of breast cancer. If estrogen is too high, it is recommended to consult a doctor for timely examination and treatment, such as cervical cancer screening or HPV test. 3. Decrease of progesterone: Generally low progesterone may cause symptoms such as breast swelling and pain, you can use dydrogesterone tablets and progesterone to maintain the luteal function under doctor’s guidance. If you find discomfort caused by breast nodules, you should seek medical advice immediately for detailed and standardized examination and treatment.
