Verified step by step guidance

Understand the relationship between viruses and cancer: Some viruses can integrate their genetic material into the host cell's DNA, potentially disrupting normal cell regulation and leading to cancer.

Identify examples of oncogenic viruses: Human Papillomavirus (HPV), Hepatitis B and C viruses, and Epstein-Barr virus are known to be associated with certain types of cancer.

Explore the mechanisms: Oncogenic viruses can cause cancer by expressing viral oncogenes, inactivating tumor suppressor genes, or causing chronic inflammation that leads to cancer.

Consider the evidence: Research and epidemiological studies have shown a correlation between certain viral infections and increased cancer risk.

Conclude based on the evidence: Given the established link between some viruses and cancer development, the statement 'Many viruses can cause cancer' is true.
