About this booklet

This booklet talks about the signs and symptoms of CUP. It explains how it is diagnosed and how it may be treated. We hope this booklet helps you deal with some of the questions or feelings you may have.  

We cannot give advice about the best treatment for you. You should talk to your doctor, who knows your medical history.
