Carcinogens can damage DNA through various (complex) mechanisms. One common way is by causing mutations or changes in the DNA sequence. This can happen directly by binding to the DNA molecule and causing chemical changes, or indirectly by generating reactive molecules that interact with DNA and cause modifications. These mutations can disrupt the normal functioning of genes that regulate cell growth and division, leading to the development of cancer. Additionally, some carcinogens can interfere with DNA repair processes, allowing mutations to accumulate over time and increasing the risk of cancer.
