In fact, every time you go to a hospital or medical examination center for a breast examination, whether it is a breast ultrasound, a mammogram or even an MRI of the breast, a breast classification is given, divided into grade 1, grade 2, grade 3, grade 4, grade 5 and grade 6. In essence, from a medical imaging perspective, especially for the breast, the normal state is divided into 6 grades. This is based on the medical imaging perspective, that is, the ultrasound map, the nodule is round or burr, or something like the sun’s rays, or echogenic strength, the sequence to distinguish, so how to distinguish, you friends do not have to go to know, as long as you know how to read on the line: 1, level 1 is the normal state; 2, level 2 is the basic normal, are not necessary to manage; 3, level 3 is benign The probability of nodules is the greatest, so this classification, that is, the results of ultrasound, or other examination results, divided into 3 levels, basically belongs to the consideration of the probability of benign nodules, generally do not do special treatment, then a few cases need to communicate with doctors, need to pay attention to the classification; 4, to the time of 4 levels, some doctors may be divided into more detailed, 4A, 4B, 4C, etc.. By the time you get to grade 4 you need to pay attention and probably have some risk of malignancy. So at this time the doctor will give you full communication and may make some intervention on the nodule; 5 or 5 is basically highly suspicious of cancer; 6 or 6 is already diagnosed as cancer; 7 or 0, 0 is actually not visible on examination. Therefore, breast grading is usually divided into 6 grades; grade 4 and later need to be taken seriously, grade 5 must be operated, and grade 6 has been diagnosed as cancer.
