According to the 2013 Annual Report of China Cancer Registry, Breast cancer ranks first among women’s malignant tumors, with about 210,000 new cases each year. Breast diseases have also attracted the attention of modern women. Many women will undergo regular physical examination, but many people do not know the specific meaning in the face of the classification on the examination report. Many people still struggle with their [serious illness], fear and even difficulty sitting and lying down.
At present, the common clinical diagnosis of breast diseases [Breast Imaging Report and Data System] (BI-RADS) was used to guide breast X-ray diagnosis earlier, and was extended to breast ultrasound and MRI diagnosis after 2003. Its significance at all levels is as follows:
Class I:
No abnormalities were found. That is, the breast structure is clear and no lesions were found.
Class II:
In view of benign changes, regular follow-up (e.g. Once a year) is recommended. Benign breast masses (e.g. Fibroadenoma, fibrous lipoadenoma, lipoma, etc.) and benign calcification all belong to this category. Women over 35 years old should be examined in combination with clinical examination and compared with previous examination. Regular follow-up observation is necessary.
Class III:
Benign diseases may, but need to shorten the follow-up period (e.g. Once every 3-6 months). Data show that the proportion of malignant diseases in this grade is less than 2%. This grade refers to uncertain types. Although the proportion of malignant diseases diagnosed is less than 2%, patients must be followed up for a short period of 3-6 months. If the patient is afraid of tumors and is unwilling to follow up, biopsy can also be performed to confirm the diagnosis.
Level IV:
There are abnormalities, suspicious malignancy, need biopsy clear. Imaging examination has found breast lesions, and cannot completely rule out the possibility of malignancy. Through biopathological examination, according to the degree of malignancy, and can be divided into a, b, c three levels. No matter which level below, should be timely to the regular hospital, specialist diagnosis and treatment.
Level IVa:
The possibility of malignant tendency is low. Including some palpable solid masses with clear margins; Grade IVb: moderate tendency to malignancy. The correlation between radiological diagnosis and pathological results is close to the same. In this case, biopsy is required to confirm the diagnosis. Grade IVc: High likelihood of malignancy. Includes obscure boundary, irregular solid mass or emerging fine pleomorphic cluster calcification. Pathological results are likely to be malignant.
Class V:
Highly suspected malignant lesion (almost recognized as malignant disease) requires surgical resection and biopsy. It is almost certain to be breast cancer lesion, which can be confirmed by biopsy.
Class VI:
Breast cancer, which has been confirmed by pathology as a malignant lesion, must be treated immediately.
Of course, the above is only to judge the degree of breast diseases from imaging. Grade I and II can be regarded as normal conditions. The higher the grade, the more attention should be paid to it. The specific situation should be comprehensively analyzed in combination with the judgment of clinicians.
