The treatment of breast nodules in early pregnancy should be decided according to the benignity and malignancy of the nodules. If the nodules are benign, such as cystic hyperplasia of the breast, if the pain is not obvious, special treatment may not be required and can be relieved after adjusting the diet and resting habits. If the pain is persistently aggravated, you need to take medication to control the symptoms under the guidance of a specialist, and then go to a regular hospital for breast surgery or general surgery after delivery for systematic and standardized treatment. If the nodule is malignant, such as breast cancer, surgery should be performed and the need for further pregnancy should be determined under the guidance of an obstetrician. If the nodule is benign or malignant, such as breast fibroids or intraductal papillomas, you should review the mammogram every 3-5 months during pregnancy to monitor the changes of the nodule dynamically, and if the nodule suddenly becomes malignant, it should be surgically removed in time.
