When tests have been unable to find the primary cancer, C.U.P is confirmed. This is often a difficult time and it can be hard to accept that the primary will never be found. Some people may feel relieved that the tests are over and that treatment can start. To work out what treatment to suggest your doctors will use the information they have about the cancer, including the location of the secondary cancer, test results and how likely it is to be a certain type of cancer.
For many people, C.U.P. is diagnosed at an advanced stage and treatment is unlikely to cure it. However, treatment may be able to control the cancer and improve your symptoms. It is possible that treatment may make you feel better and help you live longer. This is called palliative treatment.
