Which accurately describes the relationship between cancer risk and exposure to mutagens?
cancer risk decreases when a person is exposed to mutagens because the risk of dna mutation decreases as well.
cancer risk increases when a person is exposed to mutagens because the risk of dna mutations increases as well.
cancer risk increases when a person is exposed to mutagens because the risk of dna mutations decreases considerably.
cancer risk decreases when a person is exposed to mutagens because the risk of dna mutations increases considerably.

The correct answer is Cancer risk increases when a person is exposed to mutagens because the risk of DNA mutations increases as well.

Mutagens are those physical or chemical agents which cause changes in the genetic material of an organism. This brings mutation in the genome of the organism. Most of the mutagens are also carcinogenic in nature,  i.e they cause cancer. Example of mutagens are- Ultraviolet radiation, X- rays.

Thus, If a person is exposed to mutagens, the chances of cancer increases because mutagens increase the risk of DNA mutations.
