Answer: Any substance or physical factor that can contribute to the conversion of a healthy cell into a cancerous one is known as a carcinogen.
Step-by-step explanation:
Carcinogens are substances that promote carcinogenesis, the formation of cancer. This can be due to the carcinogen causing damage to the genome or to the cell's metabolic processes. Examples of carcinogens include certain chemicals, certain types of radiation, and certain viruses
Note that exposure to a carcinogen does not guarantee cancer will form. The body often repairs cellular damage, and other genetic and environmental factors can contribute to whether cancer forms or not
