No, they are distinct. Leukemia involves the overproduction of abnormal white blood cells, while aplastic anemia involves a severe underproduction of all blood cell types.
Yes, potential cures include bone marrow transplant (especially for younger patients) or immunosuppressive therapy. However, treatment is complex and outcomes vary.
The triad of symptoms results from low blood counts: fatigue/pallor (from anemia), frequent infections (from neutropenia), and easy bruising/bleeding (from thrombocytopenia).
No, it is a rare disease, with an incidence of about 2 cases per million people per year.
