According to the Halstedian model, even small localized tumors are increasingly recognized as having the potential to metastasize, making complete surgical excision impossible.
Answer: False
The Halstedian model suggested a local-to-lymph-node-to-body spread. While small localized tumors are recognized as having metastatic potential, the Halstedian model itself is not the source of this increasing recognition or the impossibility of excision; rather, it's a historical model contrasted with current understanding.
A pathologist's examination of a surgical specimen is primarily to confirm the type of cancer, not to ensure a margin of healthy tissue.
