Two different questions
Pathology reports often mention both grade and stage, and they answer different questions.
Grade: how the cells look
Grading assesses how closely tumour cells resemble normal tissue. Low-grade (well-differentiated) tumours look more like normal cells and often behave less aggressively; high-grade (poorly differentiated) tumours look more abnormal. Grade comes from the microscope and depends on clear, well-prepared slides.
Stage: how far it has spread
Staging describes the anatomical extent — tumour size, lymph node involvement and distant spread (the TNM system). It combines pathology with imaging and surgical findings.
Why both matter
Grade and stage together shape prognosis and treatment choices. For patients, the key message is that these are descriptive tools your medical team uses to personalise care — not verdicts to interpret alone. Always discuss your report with your doctor.
