The distributions of RS results, the quantitative single‐gene results for ESR1, PGR, and ERBB2, and other cancer‐related gene results obtained from core biopsy and excisional samples are highly overlapping, overall and when analyzed by patient age group (<50 vs ≥50 years) or by nodal status (N0, N1mi, N+, or unknown). Here, ERBB2 is linked to cancer.
