Family history of breast cancer by age group.

Family history	All ages (n = 1786)	Group I <35 years (n = 182)	Group II 35–59.9 years (n = 1213)	Group III ≥60 years (n = 391)	value
Family history of any cancer:	760 (42.6%)	86 (47.2%)	520 (42.9%)	154(39.4%)	0.1948
(i) 1st degree	496(27.8%)	37 (20.3%)	335 (27.6%)	124 (31.7%)	0.0198
(ii) 2nd degree	401(22.5%)	58 (31.9%)	279 (23%)	64 (16.4%)	<0.001
Family history of breast cancer:	385(21.6%)	44 (24.2%)	260(21.4%)	81 (20.7%)	0.6337
(i) 1st degree	208 (11.6%)	11 (6.0%)	143 (11.8%)	54 (13.8%)	0.0253
(ii) 2nd degree	177 (9.9%)	33 (18.1%)	117 (9.6%)	27 (6.9%)	0.0040

The total of first degree and second degree does not match the presented total since some cases have both first- and second-degree family history of cancer/breast cancer.
