Detailed explanation-1: -A few well-known carcinogens are asbestos, nickel, cadmium, radon, vinyl chloride, benzidene, and benzene. These carcinogens may act alone or with another carcinogen to increase your risk. For example, asbestos workers who also smoke have a higher risk of lung cancer.
Detailed explanation-2: -Carcinogens are substances that induce cancer by damaging the genome or through disruption of cellular metabolic processes. Some compounds interact directly with DNA, while others are activated to reactive molecules that can bind with DNA by covalent adducts causing mutations in genes crucial to biological processes.
Detailed explanation-3: -Radiation of certain wavelengths, called ionizing radiation, has enough energy to damage DNA and cause cancer.
