Whether a breast nodule 2cm should be removed or not is based on a combination of imaging tests as well as pathology results. If it is malignant or has a high likelihood of malignancy, surgical excision should be performed aggressively.
If the breast ultrasound, molybdenum target, and nuclear magnetic resonance imaging examination suggests that the breast nodule has a high possibility of malignancy, or the imaging grading of the breast nodule is 4b and above, or if the pathological tissue biopsy determines that the nodule is malignant, then surgical excision is required actively. Adjuvant radiotherapy or chemotherapy is also required if necessary.
If the breast nodule has a high likelihood of being benign after imaging and no malignant cells are present as confirmed by pathologic examination, the nodule can be removed without surgery, but regular follow-up observation is required. When the nodule has the possibility of enlargement or malignant change, it needs to be surgically removed as soon as possible.
Therefore, when breast nodules appear, it is necessary to consult a doctor in time and choose a reasonable method of treatment under the doctor’s guidance.
