What is a blood disease?
A person with a blood disease has a disorder that affects the cells, or natural chemicals, in the bloodstream.

The main blood cells that can be affected by a blood disease include: red blood cells (carry oxygen), white blood cells (immune system), and platelets (blood clotting).

What are the symptoms of a blood disease?
Symptoms of a blood disease depend on the underlying disorder and cell type that is affected. Red blood cell disease can cause symptoms of anemia. White blood cell disease can diminish the effectiveness of the immune system, leading to repeated infections. Platelet disease can lead to excessive bleeding and excessive bruising.

How does the doctor treat a blood disease ?
Treatment for a blood disease depends on underlying cause and may include blood transfusion, chemotherapy, and bone marrow transplantation.
