Which of the following is NOT listed as a cause of cancer?

• A. Asbestos
• B. Air pollution
• C. HPV
• D. UV rays

Answer: (B)

The main idea is that many different agents can increase cancer risk, including environmental exposures, infectious agents, and radiation. Asbestos exposure is a well-known cause of mesothelioma and lung cancer. HPV infection is a major cause of cervical cancer and is linked to other anogenital and oropharyngeal cancers. UV radiation from sunlight or tanning beds is a classic cause of skin cancers, including melanoma. Outdoor air pollution has been classified as carcinogenic to humans and is associated with an increased risk of lung cancer and other cancers. Because all four are supported as cancer risk factors, there isn’t one that truly isn’t listed as a cause; the question’s framing appears to be incorrect or misleading.
