Use it to explore immune biology, treatment research, patient advocacy, and resources as they are added. ### Pages in this hub * [What Is Cancer Immunotherapy?](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md)\ Learn how immunotherapy helps the immune system recognise or attack cancer. Explore checkpoint inhibitors, CAR-T, vaccines, cell therapies, and bi-specific antibodies. Learn some basics about the cancer immunity cylcle. Understand why results differ between tumour types, how “hot” and “cold” tumours affect treatment, what biomarkers may matter, and which safety and evidence questions to raise with a clinical team. * [T Cells in Cancer: A Patient Overview](/myhealingcommunity-docs/cancer-immunology/t-cells-overview.md)\ T cells help the immune system recognise cancer, coordinate a response, and limit harmful inflammation. Understanding their different roles can make immunotherapy terms easier to follow. It also helps you ask clearer questions about treatment goals, biomarkers, side effects, and the limits of early research. * [Gamma–delta T cells in cancer: a 2026 research review](/myhealingcommunity-docs/cancer-immunology/gamma-delta-t-cells-in-cancer-a-2026-research-review.md)\ Explore a T-cell type that can sense stressed cancer cells differently from conventional T cells. This review explains why gamma–delta therapies may help in difficult cancers, what researchers are testing in trials, and why promising early findings do not yet make these treatments standard care. ### Find the context for your question #### What treatment questions does immunotherapy raise? Start with [What Is Cancer Immunotherapy?](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md). It explains treatment types, evidence, benefits, and risks. Use these guides when you need a specific answer: * [Where immunotherapy works well and where it struggles](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#where-immunotherapy-works-well-and-where-it-struggles) explains why cancer type and setting matter. * [The cancer-immunity cycle](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#the-cancer-immunity-cycle) shows where an immune response can break down. * [Hot and cold tumours](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#hot-and-cold-tumours) explains why T cells may not reach every tumour. * [Why responses differ](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#why-responses-differ) covers biomarkers, immune context, and prior treatment. * [Questions for a clinic or treatment team](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#questions-for-a-clinic-or-treatment-team) helps prepare for appointments. #### What shapes the immune context? The immune environment includes cells, tumour signals, inflammation, and tissue access. It can influence whether immunotherapy has a realistic chance to work. * [T Cells in Cancer: A Patient Overview](/myhealingcommunity-docs/cancer-immunology/t-cells-overview.md) explains cells that immunotherapies try to activate or direct. * [Macrophages in Cancer](/myhealingcommunity-docs/macrophages-in-cancer.md) covers immune cells that may support or suppress anti-tumour responses. * [Diet and Gut Health May Shape Immunotherapy Response](/myhealingcommunity-docs/breast-cancer/er-positive-her2-negative/endocrine-therapy-resistance-and-dormancy/diet-and-gut-health-may-shape-immunotherapy-response.md) explores emerging gut, T-cell metabolism, and checkpoint-response research. #### Keep evidence and safety in view A strong rationale does not guarantee personal benefit. Check evidence for the exact treatment and cancer setting. * [Understanding evidence levels](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#understanding-evidence-levels) separates early research from established care. * [Safety and immune-related side effects](/myhealingcommunity-docs/cancer-immunology/what-is-cancer-immunotherapy.md#safety-and-immune-related-side-effects) covers risks needing prompt clinical attention. * [Testing, Monitoring & Biomarkers Overview](/myhealingcommunity-docs/testing-monitoring-and-biomarkers/testing-monitoring-and-biomarkers-overview.md) connects treatment discussions with testing and monitoring questions. {% hint style="warning" %} This information is for education only.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://myhealingcommunity.gitbook.io/myhealingcommunity-docs/cancer-immunology/cancer-immunology-overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
