Based on the information provided, what is a key strategy for lowering the risk of cancer development, particularly concerning DNA damage?

  • A: Inheriting a mutant tumor-suppressor gene.
  • B: Accumulating multiple genetic changes in a cancer cell.
  • C: Minimizing exposure to DNA-damaging agents.
  • D: Increasing the expression of tumor viruses.

Explanation

The text states, 'Because DNA breakage can contribute to cancer, it makes sense that the risk of cancer can be lowered by minimizing exposure to DNA-damaging agents, such as the ultraviolet radiation in sunlight and chemicals found in cigarette smoke.'
