What is an occult tumour?
An occult tumour is one that is hidden, or so small that it can't be found, even by the most detailed scans.
The place where a cancer begins is called the primary cancer. If a secondary cancer is found in the body, but the doctors don’t know where the cancer started, this is called cancer of unknown primary (CUP) or unknown primary cancer (UPC) or unknown primary tumour (UPT).
