Risk factors in the development of breast cancer among Indonesian women

Abstract

A case-control study to identify risk factors on the development of breast cancer among Indonesian women has been conducted using 300 triplets. Twelve potential determinant factors have been assessed using uni-variant analysis, and six of them showed significant association with breast cancer. Further analysis using logistic regression method revealed that five factors, namely late menarche OR = 2.35 (1.60-3.44), short lactation OR = 2.21 (1.02-4.78), breast trauma OR = 1.98 (1.12-3.49), excessive fat consumption OR = 1.81 (1.30-2.52), and menopause OR = 1.54 (1.15-2.05) have real effect on the development of breast cancer.
