What Do Grade and Stage Mean on a Cancer Report?
Grade and stage · say it: GRAYD and STAYJAlso written: tumour grade, cancer stage, TNM staging, histologic grade
Short answer
Grade describes how abnormal cancer cells look under a microscope. Stage describes how large a cancer is and how far it has spread.
What it means
Grade and stage are two different ways of describing a cancer, and they are often confused.
Grade comes from the pathologist looking at the cells. Low-grade cells look more like normal cells and tend to grow more slowly; high-grade cells look more abnormal and tend to grow faster. Different cancers use different grading systems.
Stage describes size and spread. Many cancers use the TNM system: T for the main tumour, N for lymph nodes, and M for spread to distant parts of the body. These are often combined into an overall stage, usually 0 to 4 (or I to IV).

📄 How it looks on a report
Grade 2. pT2 pN0 M0.
🙅 What it does not mean
- Grade and stage are not the same thing. A cancer can be low grade but higher stage, or the other way round.
- A small "p" (as in pT2) means it was measured on tissue by the pathologist, not just on a scan.
- Stage alone does not decide treatment or outlook. Other features matter too.
