2) T3 NO MO
3) T4 NO MO
4) T2 N2 M1

Answer 1

The TNM system is used for staging cancers. In the given options, T2 N2 M1 represents Stage IV colon cancer.

Step-by-step explanation:

The TNM system is used for staging cancers. In the TNM system, T represents the size and extent of the primary tumor, N represents the involvement of nearby lymph nodes, and M represents the presence of distant metastasis. In the given options, T2 N2 M1 represents Stage IV colon cancer because the tumor is larger and has spread to 2 or more nearby lymph nodes (N2) and has also metastasized to distant sites (M1).
