What are the types of myelodysplastic syndrome?
The number of blasts in the blood and bone marrow determines the type of myelodysplastic syndrome. Types of MDS include:
- Refractory anemia
- Refractory anemia with ringed sideroblasts
- Refractory anemia with excess blasts
- Refractory cytopenia with multilineage dysplasia
- Refractory cytopenia with multilineage dysplasia and ringed sideroblasts
Another subtype of MDS is called therapy-related myelodysplastic syndrome. Therapy-related MDS is caused by chemotherapy or radiation therapy for cancer.
