摘要

Higher levels of endogenous hormones have long been hypothesized to increase the breast cancer risk. In a case-control study we assessed the reproductive factors linked to breast cancer risk (age at menarche, age at menopause, breast feeding, number of full-term pregnancies, age at first full-term pregnancy) using a validated questionnaire applied by interview to 223 breast cancer women and 211 controls. We calculated odds ratio to establish the relation between breast cancer risk and hormonal factors. The trend analyses shows the increasing or decreasing risk depending on the studied reproductive factors. The data were analyzed in Microsoft Excel 2000 and Epiinfo version 3.3.2. The results were considered significant statistically in wich p<0.05. The results of the study shows that early age at menarche and late menopause was a risk for breast cancer females, whereas breastfeeding and higher parity protect against breast cancer. This results are important for hormonedependent cases of breast cancer that can be prevented by modifiable lifestyle and environmental factors.
