A predictive model of breast cancer risk is the Breast Cancer Risk Assessment Tool (BCRAT), designed by scientists at the National Cancer Institute. The objective was to determine the risk of breast cancer (BC) through the BCRAT.


A descriptive, prospective, observational study was done. We included 300 women over 35 years of age to whom we applied the BCRAT. We excluded women previously diagnosed with BC.


The predominant age range was 35-45 years with 43.3 %; married 79.3 % and 56.3 % housewives; the respondents were Hispanic population. The statistical analysis showed significant age over 50 years and family background as major risk factors, respectively (OR = 5.06, p = 0.02, OR = 27.75, p = 0.000). Previous breast biopsy increases the risk (OR = 5.3, p = 0.009).


According to the literature, the results obtained showed that sex, age over 50 years; family history and a previous conducted breast biopsy are the most important risk factors. According to the BCRAT risk was determined by averaging 0.6 probabilities to develop BC at five years in women over 35 years.
