[Correct utilization of breast cancer detection techniques in Mexican women]. / Utilización correcta de las técnicas de detección de cáncer de mama en mujeres mexicanas.

OBJECTIVE: Identify the characteristics associated with correct utilization of self examination (SE), clinical exam (CE) and mammography (MA) for breast cancer (BC) early detection. MATERIALS AND METHODS: Interviews were undertaken with 1 030 Mexican women (n=1 030), 20 to 88 years of age, regarding their reproductive and sociodemographic characteristics. An index of correct utilization was constructed based on the form and frequency practice of those techniques. RESULTS: The prevalence of correct utilization of SE was 11% and 5.4% for CE. Further, 7.6% of women 40-49 years of age with 2 or more BC risk factors had MA during the two years prior to the interview, and for 31.6% among women ≥50 years of age the MA was annually. The main determinant of MA utilization was having financial protection from either IMSS, ISSSTE or Seguro Popular. CONCLUSIONS: It is necessary to improve the correct utilization of BC detection techniques in Mexico.
