Viruses can contribute to cancer development through several mechanisms:
Direct Insertion: Some viruses integrate their genetic material into the host cell's DNA, leading to genetic mutations and oncogene activation. Chronic Inflammation: Persistent viral infections can cause chronic inflammation, which creates a microenvironment conducive to cancer development. Immune Suppression: Certain viruses can suppress the immune system, reducing the body's ability to detect and destroy cancerous cells. Protein Interference: Viral proteins can interfere with normal cellular processes, such as cell cycle regulation and apoptosis, promoting uncontrolled cell growth.
