Patients may present with breast nodules, when accompanied by symptoms such as swelling and pain, mostly related to the menstrual cycle. Review can be continued after 3-6 months with breast ultrasound, X-ray and MRI. Patients with breast nodules should pay attention to a light diet, and if the nodules increase in size during the review, it is necessary to follow the doctor’s instructions and take appropriate treatment in combination with the patient’s own condition, and if there is a tendency of malignant changes, it is necessary to do a biopsy of the pathological tissue to confirm the diagnosis.
