The median age at HL diagnosis was 22\u00a0years (interquartile range, 18\u201026\u00a0years), and nearly all patients in the BC\u2010HL group (97.9%) were diagnosed \u22658\u00a0years after radiation therapy. Overall, 56 patients in the BC\u2010HL group (21.8%) developed bilateral breast cancer. Compared with women who had BC\u2010NPM, those who had BC\u2010HL were younger (43 vs 60\u00a0years; <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001) and were less likely to present with ductal carcinoma in situ (8.4% vs 14.9%; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.001). On multivariable analysis that included adjustment for age, invasive BC\u2010HL was associated with smaller (\u22642\u00a0cm) tumor size (odds ratio, 1.64; 95% CI, 1.25\u20102.15) and upper outer quadrant tumors (odds ratio, 1.37; 95% CI, 1.04\u20101.81) compared with BC\u2010NPM. In a subset analysis of 102 women who had HER2\/<jats:italic>neu<\/jats:italic> status available, the distribution of biologic subtype was not significantly different between BC\u2010HL and
