The progression of the disease, or extent to which breast cancer has invaded the body, is defined in stages. The stages in breast cancer range from 0 to IV.
The stage is based on:
- Whether the cancer is invasive or non-invasive
- The size of the tumor
- How many lymph nodes are involved
- If it has spread to other parts of the body
