Nutritional Intervention and DNA Damage of Patients With HBOC

Breast and Ovarian Cancer Syndrome (HBOC) is characterized by mutations in tumor suppressor genes such as BRCA1 and BRCA2, which increase the carrier's risk of developing breast and ovarian cancer, especially before 40. In this pathology the DNA damage is increased because there is a state of chronic inflammation, plus the antineoplastic treatments and changes in body composition result in oxidative stress. The inductions of epigenetic changes by a nutritional intervention with an specific distribution of macronutrients, micronutrients and polyphenols, not only ensures an optimal nutritional status, but also shows a decrease in oxidative stress, and therefore in DNA damage. The aim of this study is to assess if the DNA damage in patients with HBOC decreases after the nutritional intervention.
