Cancer Immunology

Cancer immunology is a branch of immunology that focuses on the interactions between the immune system and cancer cells. It explores how the immune system recognizes, targets, and potentially eliminates cancer cells, as well as how tumors can evade immune responses. Here are key points about cancer immunology:

Immune System and Cancer: The immune system plays a critical role in surveillance and defense against cancer. It can identify and destroy abnormal cells, including cancer cells, through various mechanisms.

Immunosurveillance: This is the process by which the immune system constantly surveys the body for cells that may have become cancerous. Immune cells, such as T cells and natural killer cells, are involved in identifying and eliminating these cells.

Tumor Antigens: Tumor-specific antigens and tumor-associated antigens are molecules found on the surface of cancer cells that can trigger an immune response. Immune cells recognize these antigens as foreign or abnormal.

Immune Responses: When the immune system detects cancer cells, it can mount immune responses to eliminate them. These responses can include cytotoxic T cell activity, antibody production, and immune cell recruitment.
