Viruses can contribute to cancer through several mechanisms:
Insertional Mutagenesis: Some viruses integrate their genetic material into the host genome, disrupting normal cellular functions. Chronic Inflammation: Persistent infection can lead to chronic inflammation, which creates an environment conducive to cancer development. Oncogene Activation: Viruses can carry oncogenes, which are genes that have the potential to cause cancer. Immune Suppression: Certain viruses weaken the immune system, reducing the bodyâs ability to fight cancer cells.
