Malignancy of Unknown Origin (MUO)

A Malignancy of Unknown Origin (MUO) is the term we use when a patient is diagnosed as having cancer but the origin of the cancer cannot be identified. When an MUO is diagnosed it can be very hard to accept that even with tests, the primary cancer cannot be found. You’ll probably be coping with difficult feelings, so it is important to get the support you need.
