Abstract
BACKGROUND: The authors previously showed that women with a fibroadenoma have a relative risk of invasive breast carcinoma of approximately 2.0 compared with women of similar age from the general population. This relative risk approaches 1.0 when family history and proliferative changes in the adjacent parenchyma are removed and rises to > 3.0 if the fibroadenoma has complex histology. The risk for developing breast carcinoma in women with atypical lobular hyperplasia (ALH) and atypical ductal hyperplasia (ADH) or their minimal variants within a fibroadenoma is unknown. METHODS: The authors conducted a long-term, retrospective cohort study of 1834 women with adequate follow-up who presented with fibroadenoma at three local hospitals between 1950 and 1968. Histology was reviewed using established criteria, and the patients were categorized with ALH, ADH, minimal atypia, or no atypia. RESULTS: The overall prevalence of ALH or ADH within fibroadenomas was 0.81%. Minimal or true atypia within a fibroadenoma appeared to be correlated with proliferative disease in the adjacent parenchyma but could not predict for the presence there of well-established atypia. Only 7% of women with well-developed atypia developed invasive carcinoma on follow-up. Three women with minimal atypia developed invasive carcinoma. CONCLUSIONS: In this study of a large cohort of women with fibroadenoma, the authors found that atypia within a fibroadenoma cannot predict for the presence of atypia within adjacent breast parenchyma. They also found that atypia confined to a fibroadenoma does not incur a clinically meaningful risk of future breast carcinoma development greater than that of fibroadenoma alone.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
