Table 2: Risk of breast cancer in female Hodgkin's patients and their relatives, 1966-2014¹

Comparison	Breast Cancer HR	95% CI	P
Baseline BC risk in FDR of BC patients in Utah	1.8	(1.7-1.8)	< 0.0001
Risk in HL patients vs. controls
BC risk in HL patients when BC in FDR	3.8	(1.9-7.7)	0.0003
BC risk in HL patients when no BC in FDR	1.7	(1.2-2.5)	0.002
Risk in HL patients only
HL with BC in FDR vs. HL with no BC in FDR	3.3	(1.6-7.1)	0.002
HL with BC in FDR vs. HL with no BC in FDR, for HL diagnosed 1966-1999	3.7	(1.7-7.9)	< 0.001
Risk in FDR of HL vs. FDR of controls:
FDR of HL patients with BC	2.8	(1.4-5.6)	0.005
FDR of HL diagnosed 1966-1999 with BC	2.9	(1.4-5.9)	0.003
FDR of HL patients with no BC	1	(0.8-1.4)	0.97
FDR of HL diagnosed 1966-1999 with no BC	0.9	(0.6 - 1.2)	0.38

¹Adjusted for race/ethnicity and age.

FDR: First-Degree Relative; HL: Hodgkin's Lymphoma; BC: Breast Cancer.
