## **Core Concept**
The management of liver metastasis from colorectal cancer involves a multidisciplinary approach, considering the size, number, and location of metastases, as well as the patient's overall health. For a single liver metastasis of 2cm, potentially curative treatments are considered.

## **Why the Correct Answer is Right**
Surgical resection is the only potentially curative treatment for colorectal liver metastases. For a single, small liver metastasis like the one described (2cm), resection could offer a chance for cure or significant prolongation of life. The rationale behind surgical intervention is to remove all known disease, offering a potential for long-term survival or even cure.

The decision to operate is based on the patient's performance status, liver function, and the technical resectability of the metastasis.
