is leukemia diagnosed?
and marrow cells are evaluated. In addition, doctors will take
a blood sample to conduct a complete blood count (CBC). Blood
cells will be stained for examination of leukemic blast cells.
If abnormal blood test results occur, a bone marrow sample will
be obtained. Immunophenotyping is a test that involves detection
of leukemic cells by recognizing unique surface proteins. Another
test, called computed tomography (CT), scan images of the spleen
and lymph nodes to examine for enlargements. In addition, cytogenetic
testing is used to detect chromosomes' abnormalities.
are possible causes of leukemia?
indicate that leukemia is not inherited nor is it contagious.
Although scientists have been unable to pinpoint the exact cause.
Several factors are suspected.
factors such as
high-dose radiation or exposure to certain toxic chemicals (atomic
bombs) may trigger the development of leukemic cells.
Birth Defect such
as Down's Syndrome provides higher risk for leukemia.
of exposure to high
level x-ray radiation will increase susceptiblity
for leukemic development.
the inhalation of toxic vapor such as benzol vapors causes a variety
of blood disorders, including leukemia.
cause leukemia in animals. However, in humans, viruses cause only
one rare type of leukemia. Even if a virus is involved, leukemia
is not contagious.
may be a genetic predispositon to leukemia. There are rare families
with people who are born with chromosome damage. These people
have genes that increase their chances of developing leukemia.
