What does bi-rads grading mean?

1 and 0 lesions need to be re-imaged.

2. Postoperative follow-up was 65438 0 cases (negative) or 2 cases (benign).

3. Lesions classified into three categories (which may be benign) should be closely followed up (after an interval of 6 months, routine molybdenum target photography followed up for 3 years).

4. For lesions classified as grade 4 (suspicious) or grade 5 (highly suggestive of malignant tumor), biopsy should be performed.

5. The histopathological diagnosis of malignant lesions is divided into 6 categories (confirmed cancer).

Extended data:

With the development of imaging technology and the wide application of needle aspiration biopsy technology, the accuracy of preoperative diagnosis of breast lesions has been greatly improved, but in most cases, the differential diagnosis of benign and malignant lesions still needs histopathological diagnosis, which provides accurate and reliable basis for clinical treatment scheme selection and prognosis judgment.

However, it must be emphasized that pathological examination also has certain limitations. In fact, not all forms have clear boundaries. Sometimes, there are benign and malignant tumors, and it is not uncommon for tumors and sarcomas to be indistinguishable.

Bi-RADS (Breast Imaging Reporting and Data System) is a "Breast Imaging Reporting and Data System" recommended by the American Radiological Society. This kind of report is more standardized. The meaning of each classification is as follows:

Level 0: It needs to be recalled and evaluated after other inspections. Explain that the information obtained by the inspection may be incomplete.

Level 1: No abnormality was found.

Grade II: Considering benign changes, it is recommended to follow up regularly (for example, once a year).

Grade III: Benign diseases are possible, but the follow-up period needs to be shortened (for example, 3-6 months 1 time), and the proportion of malignant diseases at this level is less than 2%.

Grade Ⅳ: There are abnormalities, and the possibility of malignant lesions cannot be completely ruled out, so biopsy is needed for diagnosis.

IVa grade: low possibility of malignancy.

IVb grade: moderate malignant tendency.

IVc grade: high possibility of malignancy.

Grade V: highly suspected malignant disease (almost certainly malignant disease), requiring surgical resection and biopsy.

Grade ⅵ: Malignant lesion confirmed by pathology.
