Essay About Transformation Of Normal Blood And Abnormal White Blood Cells

Leukemia
Join now to read essay 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 Leukemias are located in
the microscope and by how much protein they
contain. These Leukemias 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. Todays 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
1990s. Scientists that study the cause of
Leukemia have not had very much success lately.
Very large doses of x-rays can increase the
efficacy growth of Leukemia. Chemicals such as
Benzene also may increase the risk of getting
Leukemia. Scientists have tried experiments on
Leukemia in Animals by transmitting RNA into the
