Leukemia

Leukemia is a disease characterized by the formation of abnormal numbers of
white blood cells, for which no certain cure has been found. Leukemia is also
conditions characterized by the transformation of normal blood-forming cells
into abnormal white blood cells whose unrestrained growth overwhelms and
replaces normal bone marrow and blood cells. Leukemias are named according to
the normal cell from which they originate, such as Lymphocyte Leukemia.
Lymphocyte Leukemia is where a Lymphocyte cell is transformed into a Leukemia
cell. Another example of Leukemia is Myelocytic or (Granulocytic Leukemia). This
forms when a Myelocytic cell is changed or transformed into a Leukemia cell.
Different Leukemia's are located in the microscope and by how much protein they
contain. These Leukemia's are usually very severe and need treatment right away.
The present incidence of new cases per year in the United States is about 25 to
every 100,000 persons. The danger to the patient lies in the growth of these
abnormal white cells, which interfere with the growth of the red blood cells,
normal white blood cells, and the blood platelets. The uncontrolled growth of
the abnormal white cells produces a tendency to unstop bleeding, the risk of
getting serious infection in the wounds, and a very small possibility of
obstruction of the blood vessels. Treatment of these Leukemias include
chemotherapy with alkylafing agents, or antimetabodies that suppress the growth
of abnormal white cells. Another treatment of some kind would be the x-ray or
the administration or radioactive substances, or radiophosphorus, may be used.
After treatment these diseases may last for many years. Age of the person
diagnosed with Leukemia does play an important part in how that individual
responds to any treatment. The older the person the less response he may have to
treatment. Leukemia in Animals white blood cells is much less common as Leukemia
in humans white blood cells. Today's treatment mostly includes chemotherapy and
or bone marrow transplantation supportive care, where transfusions of blood
components and prompt treatment of complicating infections, is very important.
Ninety percent of children with Acute Lymphocyte Leukemia have received
chemotherapy and fifty percent of theses children have been fully cured of
Leukemia. Treatment of AML or Acute Myeolcytic Leukemia is not as successful but
has been improving more and more throughout the 1990's. Scientists that study
the cause of Leu...
