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

Patients who become lost to follow-up during a clinical research trial result in many negative effects on the outcome of the trial and on the pharmaceutical company sponsoring the clinical research trial. [2] Patients who are lost-to-follow-up lead to incomplete study results, which in turn can put a bias on the result of the study as well as a ...
