Leukemia is a group of blood cancers that typically starts in the bone marrow and produces abnormal immature cells (blasts).
Leukemia (also spelled leukaemia) is a group of blood cancers that usually begin in the bone marrow and lead to the production of very large numbers of abnormal, immature blood cells called blasts (leukemia cells). Because these cells are not fully developed, they interfere with the body’s normal production of blood cells, which can result in problems such as bleeding, anemia, and frequent infections. The basic mechanism involves malignant transformation of blood-forming cells in the bone marrow. This causes abnormal proliferation of the cancerous cells and crowding out of healthy marrow cells. As the disease progresses, leukemia cells may spill into the bloodstream and spread to other organs. Leukemia is broadly divided into acute and chronic forms: acute leukemia is characterized by a rapid rise in immature cells and requires prompt treatment, while chronic leukemia involves an excessive buildup of more mature (but still abnormal) blood cells that often progresses more slowly and may be monitored before treatment.
Leukemia is a group of blood cancers that typically starts in the bone marrow and produces abnormal immature cells (blasts).
Malignant cells crowd out normal blood cell production, leading to symptoms related to low platelets, anemia, and impaired immune function.
Leukemia is broadly classified as acute (rapid increase in immature cells) or chronic (slower buildup of abnormal, relatively mature cells).
A group of blood cancers that usually originate in the bone marrow and produce abnormal blood cells called blasts.
Immature blood cells produced in excess in leukemia that are not fully developed and disrupt normal blood formation.
A leukemia type marked by a rapid increase in immature blood cells that crowds out healthy marrow and requires immediate treatment.
A leukemia type characterized by an excessive buildup of relatively mature but abnormal blood cells that typically progresses more slowly.
The tissue inside bones where blood cells are produced; it is the usual starting site of leukemia.
