What are myelodysplastic syndromes (MDS)?

Myelodysplastic syndromes (MDS) are a group of diseases that affects the bone marrow's ability to make healthy blood cells. It is a type of cancer and sometimes may be referred to as bone marrow failure. All blood cells in a healthy person are made in the bone marrow.

With MDS, your bone marrow makes a large amount of faulty cells and many die before they reach your bloodstream. These faulty or abnormal blood cells are called ‘dysplastic’. As a result, you do not have the correct number of healthy blood cells in your bloodstream.

In Ireland, around 180 people are diagnosed per year. It can be diagnosed at any age but is more common as people get older.*
