But the number of cases diagnosed in the advanced stages will increase with the more recent AJCC eighth edition of the staging criteria. After someone is diagnosed with breast cancer, doctors will try to figure out if it has spread, and if so, how far.

The staging system most often used for breast cancer is the American Joint Committee on Cancer (AJCC) TNM system. The earliest stage breast cancers are stage 0 (carcinoma in situ).

The most recent AJCC system, effective January 2018, has both clinical and pathologic staging systems for breast cancer: In both staging systems, 7 key pieces of information are used: In addition, Oncotype Dx® Recurrence Score results may also be considered in the stage in certain circumstances. If the area of cancer spread is at least 0.2 mm (or 200 cells), but still not larger than 2 mm, it is called a micrometastasis (one mm is about the size of the width of a grain of rice). The abbreviation "i+" means that a small number of cancer cells (called isolated tumor cells) were seen in routine stains or when a special type of staining technique, called immunohistochemistry, was used. As a rule, the lower the number, the less the cancer has spread. The advantage of AJCC eighth criteria compared with the AJCC seventh is the finer stratification of stages by the addition of biological factors to the anatomical classification.

Once all of these factors have been determined, this information is combined in a process called stage grouping to assign an overall stage. (This test is not often used to find breast cancer cells in lymph nodes because the results do not influence treatment decisions.). cM0(i+): Small numbers of cancer cells are found in blood or bone marrow (found only by special tests), or tiny areas of cancer spread (no larger than 0.2 mm) are found in lymph nodes away from the underarm, collarbone, or internal mammary areas.
