Myelodysplastic syndromes are blood disorders. They are also called myelodysplasia or MDS for short.
MDS blood cells have changes in them that make them develop abnormal cells. They might not need treatment for many years, but some go on to develop into acute myeloid leukaemia (AML). This means that they are cancer but how they progress will depend on the type that you have and the risk of them going on to develop into AML.
