Template:Breast cancer staging
Stage by the TNM system as follows in sections below.
Also, look for any angiolymphatic invasion. If present, check whether it reaches outside the tumor, and if so, how far. Give greatest dimension (,or 3 dimensions, generally by adding up the estimated thicknesses of involved slices)).
Primary Tumor (T)
Tumor – Depends on the tumor at the primary site of origin, as follows:
Regional Lymph Nodes (N)
Lymph Node: The lymph node values depend on the number, size and location of breast cancer cell deposits in various regional lymph nodes, such as the armpit (axillary lymph nodes), the collar area (supraclavicular lymph nodes), and inside the chest (internal mammary lymph nodes.) Each stage is as follows:
Critical numbers of involved nodes: 1-3, 4-9, and 10 and over. Note any extranodal extension.
Distant Metastases (M)
A combination of T, N and M, as follows:
