What is cancer of unknown primary (CUP)?
Cancer of unknown primary is when doctors are not sure where a cancer started in the body. It is sometimes called CUP for short.
Cancer can lead to extra expenses. By assessing your situation, you can plan ahead to meet your needs.
Our volunteers offer practical and emotional support to people affected by cancer. We want to make sure no one goes through cancer alone.
