Why type and stage matter
Your care team describes breast cancer in a few ways — the type of cells involved, the receptor status, and the stage. Together these help guide the most fitting treatment for you.
This page explains the ideas in general terms. Only your team can tell you your specific type and stage and what they mean for your care.
Terms in plain words
- Type: describes where the cancer started and how the cells look.
- Receptor status (such as hormone or HER2): whether cells respond to certain signals, which can guide treatment.
- Stage: describes size and whether it has spread beyond the breast.
- In situ vs. invasive: whether cells are contained or have moved into nearby tissue.
Key takeaways
- Type, receptor status, and stage together guide treatment.
- These are general ideas — your team gives you your specifics.
- Ask your team to explain your report in plain language.
