It should be noted that in Mexico they eat a lot more corn, cayenne, jalapeno and chile pepper. Corn contains IP6, which is a potent anti carcinogen.
This is study of Mexico where it is noted fewer women get breast cancer.

Conclusions: In this population, high intakes of folate and vitamin B12 were independently associated with decreased breast cancer risk, particularly among postmenopausal women. (Cancer Epidemiol Biomarkers Prev 2006;15(3):443–8)
**********************************
Various dietary factors have been hypothesized to be determinants of breast cancer, but few have been unequivocally associated with the disease. In contrast with most known risk factors for breast cancer, dietary factors are potentially modifiable,
making their identification essential.
The incidence of breast cancer in Mexico is still relatively low as compared with Western countries (1). However, recent changes in reproductive patterns, diet, and life-style are likely to contribute to increasing breast cancer incidence in Mexico. From 1979 to 2000, age-standardized mortality almost doubled from 6.4 to12.2 deaths per 100,000 women (2).
Low vegetable and fruit intake (97% of Mexican women consume <400 g/d or less than four servings per day) and increasing consumption of processed foods may account for the high prevalence of micronutrient deficiencies observed in Mexican women (3).
According to the 1999 National Nutrition Survey, median folate intake among Mexican women was 221 µg/d and median vitamin B12 intake was 1.6 µg/d, both close to half of the U.S. recommended dietary allowance (4). Based on a subsample of 461 Mexican women from the National Nutrition Survey, 35% of Mexican women had serum folate levels below the normal 3 ng/mL threshold, and 17% had vitamin B12 serum levels below the reference
range.3
For all women, greater intakes of folate, vitamin B6, and vitamin B12 were associated with lower risk of breast cancer (Table 2). After adjusting for age, socioeconomic status, family history of breast cancer, menopausal status, parity, availability of BMI, total caloric intake, dietary fiber, animal fat intake, total carbohydrate, and polyunsaturated fat intake; the ORs for the highest quartile of intake compared with the lowest (ORQ1-Q4) were 0.64 (95% CI, 0.45-0.90) for folate intake, 0.84 (95% CI, 0.61-1.18) for vitamin B6 intake, and 0.32 (95% CI, 0.22-0.49) for vitamin B12 intake. However, a significant inverse trend was observed only between folate intake (P, test for trend = 0.009) and vitamin B12 intake (P, test for trend =0.0001) and breast cancer risk. |
