Glossary term · Treatment
Immunotherapy (also: Cancer immunotherapy, Immune checkpoint inhibitors): Immunotherapy is cancer treatment that uses substances made from living organisms to strengthen or direct the immune system against cancer cells.
Immunotherapy is cancer treatment that helps your immune system fight cancer. The US National Cancer Institute describes it as a form of biological therapy, using substances made from living organisms. Types include immune checkpoint inhibitors, T-cell transfer therapy such as CAR T-cell therapy, monoclonal antibodies, treatment vaccines and immune system modulators.
What are the main types?
- Immune checkpoint inhibitors: drugs that block checkpoints that normally restrain immune responses, so immune cells respond more strongly to cancer.
- T-cell transfer therapy: immune cells are collected, modified or selected in a laboratory, grown and infused back. CAR T-cell therapy is one form.
- Monoclonal antibodies: laboratory-made proteins that bind to targets on cancer cells.
- Treatment vaccines: vaccines that boost the immune response to cancer cells.
- Immune system modulators: agents that enhance the immune response.
How is it given?
NCI says immunotherapy can be given into a vein, by mouth, as a cream for very early skin cancer or directly into the bladder. It is often given in an outpatient unit. Schedules range from daily to monthly, and some types are given in cycles.
How are side effects different?
NCI explains that many side effects happen because the activated immune system also attacks healthy cells and tissues. They can appear in different organs. Report new symptoms promptly, even after you return home.
What should international patients ask?
- Is immunotherapy suitable for my cancer type, and which tests guide that decision?
- How often will doses be given, and can later doses be given at home?
- Is the same drug available in my country if treatment continues there?
- Who will monitor immune side effects, and how quickly can I reach the team?
NCI says doctors check response through examinations, blood tests and scans. Your oncologist decides whether immunotherapy is appropriate.
Questions people ask
Is immunotherapy suitable for every cancer?
No. It is used for some cancer types and situations, and the oncologist decides based on the cancer and test results. A second opinion can help you understand whether it is an option in your case.
Can I travel home between immunotherapy doses?
Some patients do, depending on the drug, schedule and monitoring needs. Agree in writing who will give later doses and manage side effects before you leave India.
