Mammogram usually refers to a mammogram, which is a graded diagnostic standard for mammograms, with mammogram grade 3 indicating a high likelihood of a benign breast mass. Mammogram, also known as mammography, is usually graded from 0 to 6. 0 to 6 is the most common diagnostic criterion. It is usually graded 0 through 6. Grade 0 indicates that the evidence is incomplete and needs to be obtained again for evaluation. Grade 1 indicates a negative image, grade 2 indicates a benign nodule, grade 3 indicates a breast tumor that is more likely to be benign, and grade 4 is divided into three subgrades: 4A indicates a low degree of malignancy, 4B indicates a moderate degree of malignancy, and 4C indicates a high degree of malignancy that is not as typical as grade 5. 5 is highly suggestive of malignancy, and 6 is a malignant result confirmed by pathologic biopsy. Thus, a mammogram grade 3 would indicate a high likelihood of benign lesions, with malignant lesions typically around 2%. In this case, you should go to the hospital every 3 months to 6 months for a follow-up examination and receive timely treatment according to the examination results under the guidance of your doctor.
