This booklet has been prepared to help you understand more about cancer of unknown primary (CUP). Many people feel shocked and upset when told they have cancer. It can be even more distressing if the cancer has spread and the original (primary) site cannot be found. You may find it hard to believe that modern medicine cannot find where the cancer started.
We hope this booklet helps you, your family and friends understand how CUP is diagnosed and treated. We cannot give advice about the best treatment for you. You need to discuss this with your doctors. However, this information may help you think about what to ask your treatment team.
This booklet does not need to be read from cover to cover - just read the parts that are useful to you. Some medical terms that may be unfamiliar are explained in the glossary. You may also like to pass this booklet to family and friends for their information.
