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.

Help us keep everyone safe this winter

We’re asking everyone to please help protect our patients, visitors and employees during the winter months.

If you’re feeling unwell, please don’t visit our hospitals - even for appointments or to see loved ones, unless it’s in exceptional circumstances such as end-of-life care or maternity.

Colds, flu, Covid and norovirus (sickness and diarrhoea) can spread easily and cause serious illness in vulnerable patients.

Please only come in once you’ve been free of symptoms for at least 48 hours.

When you do visit:

 Thank you for helping us keep everyone safe this winter.
