Gross examination
As per:
or mastectomy.
Microscopic evaluation
Malignant cells having penetrated the basement membrane.
Staging
TNM staging is the most common system for invasive carcinomas.[1]
For lymph nodes (N):[1]
- Clusters <0.2mm can be called "isolated tumor cell clusters"
- Clusters 0.2 - 2.0 mm: "Micrometastasis"
- At least one carcinoma focus over 2.0 mm: "Metastasis". If one node qualifies as metastasis, count all other nodes even with smaller foci as metastases.
Critical numbers of involved nodes: 1-3, 4-9, and 10 and over. Note any extranodal extension.[1]
