pN2 TNM Finding

**Semantic type:** Finding

**Definition:** A pathologic regional lymph nodes TNM finding. The definition of pN2 finding depends on the particular type of cancer that it refers to; for example, for breast cancer, pN2 finding is defined as follows: cancer with metastases in 4 to 9 axillary lymph nodes, or metastases in clinically detected internal mammary lymph nodes in the absence of axillary lymph node metastases. "Clinically detected" is defined as detected by imaging studies (excluding lymphoscintigraphy) or by clinical examination and having characteristics highly suspicious for malignancy or a presumed pathologic macrometastasis based on fine needle aspiration biopsy with cytologic examination; for colorectal cancer, pN2 stage finding is defined as follows: cancer with metastasis in four or more regional lymph nodes.
