What causes myelodysplastic/myeloproliferative diseases?

The causes of myelodysplastic/myeloproliferative diseases are not fully understood. Normally, the production of blood cells in the bone marrow is tightly regulated. Stem cells may develop into red blood cells, white blood cells, or megakaryocytes. Megakaryocytes form platelets, which prevent small cuts from bleeding excessively. Mutations of genes involved in the formation of blood cells can lead to abnormalities in blood cell production and development, resulting in myelodysplastic/myeloproliferative disease.

Hematologic/Blood Cancers

Caused when our bone marrow makes too many blood cells, cancers of the blood lead to anemia, frequent infections and excessive bleeding.Common types of blood cancer, also called hematologic cancer, are leukemia, lymphoma and multi...

ple myeloma. These three cancers form when abnormal white blood cells crowd out the healthy ones that are responsible for fighting infections. Other myeloma disorders cause too many red blood cells and excessive platelets to be produced. When this happens, we become more susceptible to abnormal blood clotting or excessive bleeding. Although the exact cause of blood cancers are unknown, your risk increases as you get older and if you are exposed to excessive radiation or certain chemicals. You are also more vulnerable to these diseases if you are a male. See your doctor if you have fever and night sweats, pain in your stomach, or swollen lymph nodes.
