All About Immunotherapy
What is immunotherapy, and how is it different from chemotherapy? A complete guide to checkpoint inhibitors — how they work, what to expect, side effects that need urgent attention, and diet during treatment.
What exactly is immunotherapy? Is it different from chemotherapy? Are there different kinds of immunotherapy, and which one are you receiving?
This hub answers those questions and explains why most of the articles in this series focus on checkpoint inhibitor immunotherapy — the type most patients in India actually receive.
What most patients want to know before they start
- Immunotherapy helps your own immune system recognise and fight cancer — it is not a gentler form of chemotherapy.
- For most solid cancers, the immunotherapy patients receive is a checkpoint inhibitor.
- Biomarker tests such as PD-L1, TMB, and MSI help guide decisions, but they cannot predict with certainty who will benefit.
- Immunotherapy is not side-effect free — it can cause immune-related inflammation in normal organs.
- Tell every doctor you see that you are on immunotherapy — early recognition of side effects prevents serious complications.
- There is no special immunotherapy diet; probiotic supplements need caution — discuss them with your oncologist.
