Living with Myelodysplastic syndrome

A group of blood conditions in which bone marrow doesn't make healthy blood cells, causing low blood counts.

Understanding Myelodysplastic syndrome

Myelodysplastic syndromes (MDS) are a group of blood conditions in which blood cells develop abnormally in the bone marrow.

People with MDS have low blood cell counts. In some people, MDS can progress to bone marrow failure or turn into acute leukemia. It happens when a cell with a genetic change copies itself and crowds out healthy stem cells in the bone marrow. It can come from a genetic predisposition or from DNA injury from chemotherapy or radiation. Often there's no obvious cause.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Dizziness
  • Tiredness (fatigue) and weakness
  • Shortness of breath
  • Bruising and bleeding
  • Frequent infections
  • Headaches

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include blood and bone marrow specialists and cancer specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Aplastic Anemia and MDS International Foundation and The MDS Foundation may keep lists of experts for this condition.
