A breast nodule elasticity score of 4 generally suggests that a breast nodule may have a malignant potential, and pathology is usually required to clarify the nature of the nodule. Breast ultrasound elastography belongs to an evaluation of benign and malignant breast lesions. Breast elastography is standardized into a score of 5, with the higher the score the greater the likelihood of malignancy. An elasticity score of 1 indicates that the whole or most of the breast is soft and elastic, indicating that the breast is normal and there are no nodules or masses. Elasticity score of 2, localized lesions are slightly tough and the surrounding tissue is soft and elastic, indicating the presence of localized breast nodules or masses. With an elasticity score of 3, the patient may present with larger breast nodules; more severe cases of breast hyperplasia are generally benign. With an elasticity score of 4, the lesion site and surrounding tissues become hard, and the lesion site is even harder, suggesting that the mass has the possibility of malignancy, and it is recommended that the diagnosis be clarified and then surgical treatment be carried out in time. Elasticity score of 5, the lesion site and the surrounding breast tissue have a harder texture, suggesting that the mass is more malignant, suggesting timely surgery and pathologic examination. It is recommended that people with breast nodule elasticity score of 4 should consult a regular hospital in time and under the guidance of a doctor to avoid delaying the condition.
