Clinical characteristics of breast cancer patients with family history.

This study was conducted to acquire information as to the clinicopathological characteristics of breast cancer patients with family history. Of 583 patients with breast cancer, 60 (10.3%) had family history in at least one relative within the second-degree. The affected family member was most frequently a sister (43%), followed by the mother (23%) and an aunt (20%). Comparison of the data for the patients between with and without family history revealed no significant differences for any of mean age, menopausal status, histological type, histological staging, and estrogen receptor status. Although the sample size was small, neither the survival rate nor the bilaterality of disease was influenced by the family history of breast cancer.
