Your hospital team will recommend the best treatment for you and help you with any side effects from your treatment.
Tests for MDS
If your doctor thinks you might have MDS, they'll do some tests to find out more. After diagnosis you'll have tests to monitor the MDS and to check if any treatment is working.
Active monitoring (watch and wait)
Some people with MDS don't need treatment straight away. If you don't need treatment, you'll go on active monitoring (watch and wait).
