Abstract

Breast cancer (BC) is a foremost type of cancer in women globally with an increased mortality rate in developing countries. Information regarding hereditary factors, lifestyle, work environment, food habits, and personal history could be useful in diagnosing breast cancer. Among such food habits, the reuse of edible oil for preparing food is a common practice in any developing country. The repeated heating of oils enhances the oxidative degradation of oil to produce polyaromatic hydrocarbons (PAH) which could disrupt the redox balance and generate reactive oxygen species. These reactive toxic intermediates can lead to BRCA1 mutations that are responsible for breast cancer. Mutations in DNA are the main cause for the conversion of proto-oncogenes into oncogenes which leads to change in expression and an increase in cell proliferation wherein a normal cell gets transformed into a malignant neoplastic cell. This review summarizes the possible mechanism involved in the induction of breast cancer due to repeated heating of edible.

Keywords: BRCA1; DMBA; Repeated heat oil; breast cancer; polyaromatic hydrocarbon.
