Compared to non‐Hispanic White people, Hispanics had significantly higher relative risk of advanced stages at presentation (RRR = 1.69, P < 0.001), triple‐negative tumors (RRR = 1.98, P < 0.0001), HER2 + /ER‐/PR‐ disease (RRR = 1.61, P = 0.01), and less ER+/PR+/HER2− BC (RRR = 0.76, P = 0.002). Here, ESR1 is linked to breast cancer.
