Employing physical examination, mammography, and fine-needle aspiration (FNA) in the evaluation of palpable breast masses, the Oregon Health Sciences Group studied almost 500 women prospectively, assigning a score of 1, 2, or 3 for benign, suspicious, or malignant results. The triple test score (TTS) is the sum of these observations. They noted that all lesions with a TTS of 4 or lower were benign on follow-up (n = 315), and those masses with a TTS of 6 or higher (n = 130) were confirmed malignant on biopsy. Of the 39 lesions (8%) with a score of 5, 19 were malignant and 20 were benign. This was, in their opinion, a clear-cut separation. Simple measures can provide definitive answers for palpable breast masses, with apparent safety and reliability.
