Reproductive risk factors differ among breast cancer patients and controls in a public hospital of Paraiba, northeast Brazil.

The incidence and mortality rates of breast cancer in Northeast Brazil are increasing and little is known about prevailing reproductive factors contributing to this increase. A case-control study was conducted in a public hospital of Campina Grande, state of Paraiba, including 81 women with diagnosed invasive breast cancer and 162 age matched (±5 years) controls. Binominal logistic regression analysis was applied to estimate odds ratio (OR) and confidence intervals (CI) of risk factors.
