IntroductionPrevention programs have not achieved the expected results in preventing mortality from breast and cervical cancer in Mexico. Therefore, we propose a complementary strategy.MethodologyAn educational strategy for high school students in Mexico (2011–2013) was designed (longitudinal design, two measurements and a single intervention). The postintervention assessment included: 1) knowledge acquired by students about cancer prevention and 2) The performance of the student as a health promoter in their household. The strategy was based on analysis of cases and developed in three sessions. An assessment tool was designed and validated (Test–Retest). The levels of knowledge according to the qualifications expected by chance were determined. Wilcoxon test compared results before and after intervention.ResultsAn assessment instrument with 0.80 reliability was obtained. 831 high school students were analyzed. Wilcoxon rank-sum test showed a significant learning after the intervention (Z = − 2.64, p = 0.008) with improvement of levels of knowledge in a 154.5%. 49% of students had a good performance as health promoters.ConclusionsThe learning in preventive measures is important to sensitize individuals to prevention campaigns against cancer. This strategy proved to improve the level of knowledge of students in an easy and affordable way.

Objective: To assess if nutritional intervention with a diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) decreases acute gastrointestinal toxicity induced by pelvic external beam radiotherapy in patients with gynecologic tumors. Material and methods: Single-center, randomized, prospective clinical trial comparing patients on a low-FODMAP diet vs. standard Mexican diet, designed to detect an 80% decrease in Grade 1-2 acute gastrointestinal toxicity in the standard diet group to 25% of Grade 1-2 acute gastrointestinal toxicity in the low-FODMAP diet group. Results: Thirteen patients were recruited per group, with higher gastrointestinal toxicity grade 1-2 (85 vs. 77%) and 3 (23 vs. 0%) being reported in the standard diet group with regard to the low-FODMAP diet (p = 0.16). The low-FODMAP diet group had a lower end of treatment symptom score in the cervical cancer patient quality of life questionnaire (1.41 vs. Nutritional intervention to reduce EBRT induced GI toxicity 85
