Immunotherapy: Introduction, Procedure and Uses
Introduction
Immunotherapy is a modern treatment method that uses the body's own immune system to fight diseases, especially cancer. Normally, the immune system identifies and destroys harmful cells. However, cancer cells can hide from immune defenses. Immunotherapy helps the immune system recognize and attack these abnormal cells more effectively. It is considered one of the most promising advances in biotechnology and medicine because it provides targeted treatment with fewer side effects than traditional therapies in many cases.
Procedure of Immunotherapy
Diagnosis and Evaluation
Doctors identify the type and stage of disease and determine whether immunotherapy is suitable.
Selection of Immunotherapy Type
Types include monoclonal antibodies, immune checkpoint inhibitors, cancer vaccines, and CAR-T cell therapy.
Administration
The treatment is usually given through intravenous (IV) infusion, injection, or oral medication.
Immune System Activation
The therapy stimulates immune cells, especially T-cells, to recognize and attack diseased cells.
Monitoring and Follow-up
Patients are regularly monitored for treatment response and possible side effects.
