| 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) | p value |
|---|---|---|---|---|---|
| Family history of any cancer: | 760 (42.6%) | 86 (47.2%) | 520 (42.9%) | 154(39.4%) | 0.1948 |

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.
