The Impact of Family History of Breast Cancer on Knowledge, Attitudes, and Early Detection Practices of Mexican Women Along the Mexico-US Border

Rates of breast cancer (BC) have increased in Mexico, with the highest incidence and mortality rates observed in the northern
Mexican states. This study aimed to describe the BC knowledge, attitudes and screening practices among Mexican women with
and without a family history of BC residing along the Mexico-US border, and identify factors associated with screening behaviors.
One hundred and twenty eight Mexican women aged 40 and older completed an interviewer-administered questionnaire on sociodemographic
characteristics, knowledge, family history, and screening practices. There were no significant differences between Mexican
women with and without a family history. Over 60% of women in both groups had never had a mammogram/breast ultrasound, and
more than 50% had never obtained a clinical breast exam. Age, marital status, insurance, and breast cancer knowledge significantly
influenced BC screening behaviors among Mexican women. Further research is needed to examine other key factors associated
with screening utilization, in effort of improving BC rates.
