Infectious agents can contribute to cancer development through several mechanisms:
Chronic Inflammation: Persistent infection can lead to chronic inflammation, which in turn can cause DNA damage and promote cell proliferation. Direct Oncogenic Effects: Some viruses can integrate their genetic material into the host genome, leading to mutations and oncogenic transformations. Immune Suppression: Certain infections can weaken the immune system, making the body more susceptible to cancer. Production of Oncogenic Proteins: Some infectious agents produce proteins that interfere with normal cellular functions and promote uncontrolled cell growth.
