Immunotherapy is a type of cancer treatment that harnesses the body’s immune system to identify and fight cancer cells. Unlike traditional treatments such as chemotherapy and radiation, which directly target cancer cells, immunotherapy strengthens the immune system’s natural ability to detect and destroy cancer cells, making it a powerful and often more targeted approach to cancer care.
The immune system’s primary function is to protect the body from harmful invaders like bacteria, viruses, and abnormal cells. However, cancer cells can evade detection by the immune system, either by disguising themselves as normal cells or by suppressing the immune response. Immunotherapy works by either boosting the overall activity of the immune system or by helping it recognize and target cancer cells more effectively.
Immunotherapy is a cancer treatment that uses the body’s immune system to fight cancer cells. It helps the immune system recognize, attack, and destroy cancer cells, which it may not normally detect.
Immunotherapy boosts or modifies the immune system's natural defenses. It can help the immune system recognize cancer cells, enhance its ability to fight them, or reduce the cancer’s ability to evade immune detection.
Immunotherapy is used to treat several types of cancer, including melanoma, lung cancer, kidney cancer, bladder cancer, and lymphoma. It is also being studied for use in breast, prostate, and other cancers.
The main types of immunotherapy include: Checkpoint inhibitors: Drugs that help the immune system recognize and attack cancer cells. CAR T-cell therapy: A treatment that modifies a patient’s immune cells to fight cancer. Monoclonal antibodies: Lab-made proteins that target specific markers on cancer cells. Cancer vaccines: Help the immune system attack cancer cells by recognizing specific cancer proteins.
Immunotherapy is more targeted, potentially leading to fewer side effects than chemotherapy. It can also have longer-lasting effects by helping the immune system remember and continue to attack cancer cells even after treatment ends.
Yes, while immunotherapy can have fewer side effects than chemotherapy, it can still cause side effects such as fatigue, skin reactions (rashes, itching), flu-like symptoms, diarrhea, or more severe issues like inflammation of vital organs (e.g., lungs, liver). The severity varies from person to person.
