Differential diagnosis
In invasive ductal carcinoma, malignant cells have penetrated the basement membrane, in contrast to ductal carcinoma in situ.
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]
