Cystic nodule grade 2 is the rating of the degree of benignity and malignancy of a cystic nodule under breast ultrasound, which is almost always benign and rarely cancerous. Therefore, after having a grade 2 cystic nodule, you only need to review the mammogram regularly every 6-12 months to dynamically observe the changes in the nature of the nodule. If the nodules are found to be progressively enlarged and accompanied by painful discomfort in the course of observation, a fine needle aspiration biopsy should be performed in a regular hospital for breast surgery or general surgery in a timely manner to clarify the diagnosis, and if necessary, surgical excision should be performed. If there is no significant change in the nodules after 2 years of continuous observation, the review period can be extended to 12-24 months. In daily life, you should take light and vitamin-rich food, avoid eating too much fried and spicy stimulating food, go to bed early and wake up early, avoid staying up late, and keep your mood happy.
