A breast grade of 4c indicates a high likelihood of malignancy in breast imaging grading, but does not determine whether breast-conserving or total mastectomy is the surgical option based on a breast grade of 4c.
Breast-conserving surgery is a breast cancer resection that preserves the breast, and total resection is a total mastectomy. The specific type of surgery needs to be chosen based on the stage and grading of the breast tumor and cannot be graded solely on breast imaging. Breast-conserving surgery can be chosen when there is an indication for breast-conserving mastectomy in the case of early-stage breast cancer.
Total mastectomy is an option if the woman is older and not a candidate for radical breast cancer surgery, or if the breast cancer is graded as a microscopic carcinoma.
If during the imaging examination, the result suggests that the breast nodule is grade 4c, puncture biopsy is needed to clarify the nature of the nodule, and then according to the grading and staging of the lesion, the choice of surgical method will be made under the guidance of the doctor.
