Oncology 101: immune foundations
Start with four questions: what binds, how a response begins, what the cells can do and where the route can fail.
Cancer and immunotherapy vocabulary becomes easier when each word has a job. These lessons help you read a mechanism diagram and ask a useful next question. Each includes a fictional example and a short practice exercise.
For an ordered path that adds tissue patterns, immune measurements and treatment comparisons, use the immune-system guide. This page is the supporting lesson shelf for that path.
Choose a lesson
| Lesson | The question you will answer | Suggested minutes |
|---|---|---|
| Ask what happens after binding | Does the interaction signal, block or deliver something? | 8 |
| How dendritic cells help start a response | How does a displayed clue become a priming opportunity? | 8 |
| Why a T-cell count does not tell the whole story | What separates presence, recognition and function? | 8 |
| Find the step an immune response can lose | Which dependency failed, and what would test a bypass? | 9 |
Reading times are suggested budgets. You can pause at a linked concept or use a lesson’s “Explain it back” prompt to check your understanding.
The shared vocabulary shelf
- Messages and receivers: ligands and receptors, antibody structure, cytokines and chemokines.
- The response begins: immune-cell roster, cross-presentation, T-cell priming.
- The response changes: T-cell repertoire, T-cell states, immune checkpoints.
- The route can fail: cancer-immunity cycle, immune escape, natural killer cells and missing self.

Use standard early breast-cancer treatment for the different jobs of medicines, surgery and radiation. Use reading cancer evidence when a mechanism becomes a claim about benefit. The linked lessons carry their sources and review status; expert and learner review remain pending.
