Research Abstract |
Incidence and death rates of breast cancer in Japan have increased markedly in recently years, especially among postmenopausal women. Many gene polymorphisms of enzymes potentially related to carcinogenesis have been examined for breast cancer risk. Aromatase is one of the key enzymes in estrogen biosynthesis and encoded by CYP19A1. To evaluate impact of CYP19A1 haplotypes on breast cancer risk, we conducted a case-control study. Some haplotyeps in CYP19A1 would influence sex hormones levels, thus suggesting potential importance of CYP19A1 haplotypes on breast cancer risk.
