The presence of blood flow signals around the breast nodule suggests that the nodule is rich in blood circulation and requires attention to exclude malignant lesions. It is advisable to take a biopsy or to remove the nodule directly for pathology, which is the gold standard for diagnosis. Most benign nodules have less blood flow signals, such as breast fibroadenoma and breast cysts, while malignant tumors are rich in blood circulation and obvious blood flow signals can be seen during ultrasound examination, but blood flow signals around the nodule do not confirm the diagnosis of malignant tumor, and further examination is needed to confirm the diagnosis. The most important thing is to pay attention to the physical examination of the breast on time, and to find the nodules in the breast in time to confirm the diagnosis, or regular ultrasound follow-up observation. The breast disease will be affected by mood factors, usually try not to be grumpy, often angry, too much stress, etc., found breast nodules timely hospital consultation.
