A cancer of the blood cells There are many different types See leukaemia section
A cancer of the blood cells The blood cells begin to grow before reaching maturity This means that the 'leukaemic' or abnormal cells outnumber the normal blood cells
malignant neoplasm of blood-forming tissues; characterized by abnormal proliferation of leukocytes; one of the four major types of cancer
leu·kae·mia in AM, use leukemia Leukaemia is a disease of the blood in which the body produces too many white blood cells
A type of cancer in the bone marrow causing an abnormal increase in the amount of white blood cells produced This results in a lack of red blood cells, or anemia, and the loss of some blood-clotting ability
General term used to describe a group of malignancies of either lymphoid or hematopoietic origin; progressive proliferation of abnormal leukocytes can be found in the blood, the hematopoietic tissues, and other organs
Any of various acute or chronic cancers of the bone marrow in which unrestrained growth of blood cells occurs, often accompanied by anemia, impaired blood clotting and enlargement of the lymph nodes, liver and spleen
—Bone marrow cancers in which white blood cells divide uncontrollably, affecting the production of normal white blood cells, red blood cells, and platelets
Cancer that begins in developing cells in the bone marrow Leukemia occurs when immature or mature cells multiply in an uncontrolled manner in the bone marrow It is classified as lymphocytic or myeloid, according to the type of cell that is multiplying abnormally, and either acute, signifying rapidly progressing disease with a predominance of highly immature (blastic) cells, or chronic, which denotes slowly progressing disease with greater numbers of more mature cells
From the Greek meaning "white blood" Leukemia is a cancer of a marrow cell The disease appears in one of four major forms Acute lymphocytic or acute myelogenous leukemia characterized by the uncontrolled proliferation and accumulation of abnormal immature cells, referred to as leukemic blasts These cells fill the marrow spaces and enter the blood Chronic myelogenous leukemia and chronic lymphocytic leukemia are less rapidly progressive The former, however, requires treatment in nearly all cases at the time of diagnosis, whereas the later may, in some cases, be non-progressive for long periods
A rapidly progressing cancer (malignancy) of the bone marrow and blood characterized by an uncontrolled growth of white blood cells There are three major types
a cancer of the blood-forming tissue Leukemic cells look different than normal cells and do not function properly lymphocytic leukemia - a type of leukemia in which the cancer develops in the lymphocytes (lymphoid cells)
a type of cancer of the blood, that causes weakness and sometimes death (leukos + -aimia (from haima )). Cancer of blood-forming tissues with high levels of leukocytes. Radiation exposure and hereditary susceptibility are factors in some cases. In acute leukemias, anemia, fever, bleeding, and lymph-node swelling develop rapidly. Acute lymphocytic leukemia, found mostly in children, was once over 90% fatal in six months. Drug therapy can now cure more than half these children. Acute myelogenous (granulocytic) leukemia, found mostly in adults, has frequent remissions and recurrences, and few patients survive long. Chronic myelogenous leukemia most often begins in the 40s; weight loss, low fever, weakness, and other symptoms may not develop immediately. Chemotherapy helps the symptoms but may not prolong life. Chronic lymphocytic leukemia, mostly in the elderly, may be inactive for years. Survival rates are better than in myelogenous leukemia; most deaths are caused by infection or hemorrhage
Any of several types of cancer in which there is an abnormal growth of white blood cells in the bone marrow Leukemias are classified into acute and chronic types, and according to the type of white cell that is being abnormally produced
Cancer of white blood cells Acute leukemias are characterized by the presence of "blasts," which are immature white blood cells Large quantities of blasts generally overgrow the bone marrow, leaving very little space for normal bone marrow cells This type generally requires immediate treatment Chronic leukemias are those characterized by a large and uncontrolled growth of more mature white blood cells These types of leukemias tend not to progress as rapidly, and treatment is often milder than that of acute leukemias
