How many levels of breast hyperplasia are divided, how many levels of breast hyperplasia are there,

There are 6 grades of breast hyperplasia, and the results of the ultrasound of the breast are classified according to the Bi-RADS (American College of Radiology's recommended "mammography" reporting and data system).

BI-RADS grade 1: negative result, no abnormal lesions found.

BI-RADS grade 2: benign lesions, malignant lesions can be basically ruled out, such as unilateral cysts, intramammary lymph nodes, breast implants, fibroadenomas with stable post-surgical changes and no changes on serial ultrasound, etc., and regular re-examination is sufficient.

BI-RADS grade 3: may be benign lesions, the malignancy rate is generally 2%, and short-term (generally recommended 3 to 6 months) follow-up is recommended.

BI-RADS grade 4: suspicious malignancy, 3% 94% malignant likelihood, biopsy such as core needle biopsy (CNB), vacuum-assisted minimally invasive biopsy (VAB), or surgical biopsy is recommended. This class can be further divided into categories 4A, 4B and 4C3.

4a: Biopsy is required, but the likelihood of malignancy is low (10%). If the results of the biopsy are benign and can be trusted, it can be transferred to semi-annual follow-up.

4b: Tends to be malignant. The probability of malignancy is 10% to 50%.

4c: Further suspicion of malignancy, 50% 94% likelihood.

BI-RADS grade 5: high probability, 95% malignancy, should be aggressively diagnosed and managed.

BI-RADS grade 6: Lesions that have been confirmed to be malignant by biopsy but have not yet been performed, and aggressive ** measures should be taken.

Once breast hyperplasia is found, it is necessary to pay attention to it so as not to aggravate or even cause malignant transformation. It is generally recommended to take Lactone orally, 2 times a day, for a period of time, to regulate endocrine, so as to achieve the purpose of breast hyperplasia.

In addition, maintain a comfortable mood and optimistic mood, change the diet structure, prevent obesity, eat less fried foods, animal fats, sweets and too many tonic foods, eat more vegetables and fruits, and eat more whole grains.

BI-RADS is a mammography reporting and data system created and recommended by the American College of Radiology, and the latest grading is the fourth edition, with a total of 7 levels.

Guidance: Each level has its own imaging findings:

Grade 0: Requires further evaluation by other imaging tests or comparison with the previous film.

Grade 1: negative. No anomalous findings. Grade 2: Benign findings.

Grade 3: may be benign finding, short-term follow-up is recommended. There is a high probability of benignness.

Grade 4: suspicious abnormality, biopsy should be considered.

Grade 5: High suspicion of malignancy, appropriate clinical action should be taken (almost certainly malignancy)Grade 6: Biopsy confirmed malignancy, appropriate measures should be taken.
