Stages of cancer
Stage 1: Tumour is small and contained within the organ in which it started.
Stage 2: Tumour is larger and may have begun to spread.
Stage 3: Tumour is large and has spread into nearby tissues and lymph nodes.
Stage 4: Cancer has spread through the blood or lymphatic system to distant sites in the body.
Notes:
- Cancer incidence and stage data exclude Quebec, as data for Quebec are not available in the Canadian Cancer Registry for 2011 to 2015.
- Cancer stage data are restricted to people diagnosed at ages 18 to 79.
- Stage data do not add to 100% as a small proportion of cases could not be assigned a specific stage ('Unknown' stage).
