Findings from Chagpar et al. [74] indicate that there was no significant difference in the ER+ and PR+ tumours for Black and White women, 97.7% (n = 256/469) vs. 97.6% (n = 903/1415), (p = 0.682) and 86.0% (n = 222/469) vs 86.0% (n = 784/1415) (p = 0.873). The gene discussed is ESR1; the disease is neoplasm.
