How Do Chemical Changes Contribute to Cancer Development?
Chemical changes can contribute to cancer development through several mechanisms. One of the primary mechanisms is the mutation of DNA, which can lead to the activation of oncogenes or the inactivation of tumor suppressor genes. These genetic mutations can result from exposure to carcinogens such as tobacco smoke, UV radiation, and certain chemicals. Additionally, the epigenetic modifications, such as DNA methylation and histone modification, can also play a significant role in cancer progression.
