Carcinogens and protective genes against the cancer

Abstract

What is a carcinogen? Substances that cause severe gene damage in cells and trigger
mechanisms that lead to cancer are called carcinogens. In short, it means "cancercausing". While some chemicals found in nature can be carcinogens, there are also
carcinogens produced by humans. Carcinogens reduce the functions of cancerpreventing genes and cause mutations that damage DNA repair systems. In this
proceeding-review study we focus on some of the carcinogens and also the genes that
are protective against the cancer.
