The researchers have recruited a total of 652 women including 309 in the United States and 343 in Mexico. Women in Mexico are significantly older at diagnosis at 53.8 years compared with 48.7 years in the United States. Reproductive data showed a similar age at menarche, menopause and first pregnancy. However, the number of live births was higher in Mexico at 3.7 vs. 3.2 in the United States.
Prevalence of family history of breast cancer was significantly higher in the United States at 18.1 percent compared with 6.2 percent in Mexico.
Body mass index was similar, and high, in both groups at an average of about 29. "This abstract sets the stage for what we want to talk about because these differences and similarities could prove to be important with further research," said Martinez.

A subsequent abstract, presented by Rachel Zenuk, a graduate student at The University of Arizona Mel and Enid Zuckerman College of Public Health, suggests that breast cancer may be more aggressive in Hispanic women because they are waiting longer to receive treatment.
The data show that 67 percent of breast cancer was found through self detection, while only 23 percent was found using screening mammography and six percent through a clinical examination. Among Hispanic women born in the United States, the rate of mammography use was 83 percent compared with 62 percent among women not born in the United States.
After noticing a change in their breasts, 49 percent of women reported waiting one month or more to seek medical attention. The most common reason was that these women did not have access to insurance or
