Explanation:
Detailed explanation-1: -Certain chemicals, including benzene, beryllium, asbestos, vinyl chloride, and arsenic are known human carcinogens, meaning they have been found to cause cancer in humans. A person’s risk of developing cancer depends on how much, how long, how often, and when they are exposed to these chemicals.
Detailed explanation-2: -Some carcinogens cause cancer by changing a cell’s DNA. Others do not affect DNA directly, but lead to cancer in other ways. For example, they may cause cells to divide at a faster than normal rate, which could increase the chances that DNA changes will occur.
