What is preleukemia called?

Preleukemia is now more accurately called Myelodysplastic syndrome (MDS).

Understanding Myelodysplastic Syndrome (MDS)

Former Terminology

Before it was well-understood, MDS was often referred to as:

  • "Pre-leukemia"
  • "Smoldering leukemia"

These terms indicated that the condition could potentially develop into acute myeloid leukemia (AML), a type of blood cancer.

What is MDS?

MDS is a group of disorders where the blood-forming cells in the bone marrow become abnormal. This results in the body not producing enough healthy blood cells. MDS can impact:

  • Red blood cells: Leading to anemia.
  • White blood cells: Increasing the risk of infections.
  • Platelets: Causing bleeding and bruising issues.

Key Takeaways

  • Preleukemia is outdated: The preferred and correct term is now Myelodysplastic syndrome (MDS).
  • MDS is a precursor: MDS can sometimes progress into leukemia.
  • MDS involves abnormal blood cell production: The bone marrow produces fewer, less healthy blood cells.
