Question

Which of the following statements about cancer is FALSE?
A)Viruses cause some cancers.
B)Tobacco use is responsible for more than 20% of all cancer deaths.
C)A mutation in even a single cancer-critical gene is sufficient to convert a normal cell into a cancer cell.
D)Chemical carcinogens cause cancer by changing the nucleotide sequence of DNA.

Accepted Answer

While mutations in certain genes can significantly increase the risk of cancer, a single mutation in one cancer-critical gene is usually not sufficient to transform a normal cell into a cancer cell. Cancer typically results from the accumulation of multiple genetic alterations that together lead to uncontrolled cell growth and division.
