A BI-RADS classification of 4 or 5 warrants biopsy to further evaluate the offending lesion. [3] Some experts believe that the single BI-RADS 4 classification does not adequately communicate the risk of cancer to doctors and recommend a subclassification scheme: [4] 4A: low suspicion of malignancy, about > 2% to ≤ 10% likelihood of malignancy
BI-RADS 3 indicates probably benign. [53] BI-RADS 4 indicates suspicious for malignancy. BI-RADS 5 indicates highly suggestive of malignancy. BI-RADS 6 is for biopsy-proven breast cancer. [54] BI-RADS 3, 4 and 5 assessments on screening mammograms require further investigation with a second "diagnostic" study. The latter is a more detailed ...
Like the triple test score, BI-RADS employs a numerical scoring system to determine whether a mass is benign or malignant. The triple test score assigns a numerical indicator of 1 to 3 while BI-RADS assigns a numerical indicator of 1 to 6. The BI-RADS scoring for mammograms can be comparable to the triple test score's scoring for mammograms. [2]
Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes.
[3] [4] [5] Breast biopsies can be done utilizing ultrasound, MRI or a stereotactic biopsy imaging guidance. [2] [5] [4] [6] Vacuum assisted biopsies are typically done using stereotactic techniques when the suspicious lesion can only be seen on mammography. [5]
Dr. Kopans invented the Kopans Wire used in needle localization that made it possible for radiologists to accurately guide surgeons to lesions detected by mammography which made it possible to diagnose breast cancers at a smaller size and earlier stage excisional breast biopsies. [2]
These lesions are preceded by atypical lobular hyperplasia and may follow a linear progression to invasive lobular carcinoma (ILC), with specific genetic aberrations. [3] This process coincides with the progression of ductal neoplasia to ductal carcinoma in situ and invasive carcinoma.
