Abstract

This guideline covers diagnosing and managing secondary cancers in people aged 18 and over when the site of the primary cancer is unknown. This includes people who have had treatment for cancer before. It aims to improve quality of life by offering advice on tests for identifying the site of the primary cancer and options for managing the person’s condition when this cannot be found.

This guideline covers carcinomas only and does not cover, for example, lymphoma, melanoma and sarcoma. For other NICE guidelines on cancer, see the cancer topic page.
