How Does Duration of Exposure Influence Cancer Risk?
The relationship between exposure duration and cancer risk is multifaceted. Prolonged exposure to carcinogens increases the likelihood of genetic mutations, which can lead to cancer. For instance, long-term exposure to tobacco smoke significantly raises the risk of lung cancer. Similarly, prolonged exposure to UV radiation from the sun can lead to skin cancer. The cumulative effect of these exposures over time can overwhelm the body's natural repair mechanisms, resulting in the development of cancerous cells.
