Current use of at least 3 tablets per week of acetaminophen was not associated with breast cancer or any particular subtype of breast cancer in models adjusted for the five NSAIDS (for breast cancer, HRR = 1.00, 95% CI 0.87–1.15 for current use of 3+ tablets per week of acetaminophen (264 cases) compared to no use of acetaminophen in the last 3 years (1109 cases); for the HR-positive/HER2-negative subtype, HRR = 0.98, 95% CI 0.83–1.16 for current use of 3+ tablets per week (180 cases) compared to no use of acetaminophen in the last 3 years (757 cases); other data not shown). The gene discussed is ERBB2; the disease is breast cancer.
