Leukemia

By: Alexis Headding

Cancer is a disease of the cell cycle because it mutates cells and it changes vital DNA

- Leukemia is made in blood-forming tissue like bone marrow and spreads though out the body

- Cancer cells are different from other cells because they continue to divide because they do not have any kind of signal, like a normal cell would have, to stop dividing

-Leukemia affects the blood because it does not produce as many white blood cells as it should and the white blood cells it does produce do not mature as they are supposed to

Leukemia Symptoms

White blood cells begin to not fight off infections which can cause sickness and disease


Symptoms:

- enlarged liver

- shortness of breath

- swollen lymph glands

- easy bruising/bleeding

- frequent nose bleeds

- headaches

- bone/joint pain

- fatigue and weakness

Causes of Leukemia

Environmental-

The only two confirmed environmental issues that cause Leukemia are radiation and benzene. There are others that people think are causing it but there are only two confirmed.

Health Factors-

There is no set health defects that caused Leukemia, it is when you are exposed radiation, or benzene.

Can it be inherited?-

The disease itself cannot be inherited, but traits that cause it are passed down that have potential to cause it.

Prevention

There is nothing you can really do to prevent it, but you can stay away from high radiation and benzene chemicals.

Leukemia Treatments

Surgery will not do anything for this cancer because it is not a tumor. They have found that chemotherapy, stem cell transplantation, and blood transfusions have worked in most patients.

(the treatments vary with the type of leukemia)

How leukemia is diagnosed

They do many things to diagnose leukemia. Examples: complete blood count, bone marrow aspirate and biopsy, lumbar puncture (spinal tap), Cytochemistry and immunocytochemistry, immunophenotyping, cytogenetics (chromosome analysis), and molecular testing including polymeras chain reaction testing.

People Affected

About 43,000 people are diagnosed with leukemia each year in America. Acute Lymphocytic Leukemia is most common in children, and is responsible for 35% of cancers found in children. Chronic Lymphocytic Leukemia is mainly found in older adults. Acute Myeloid Leukemia is mainly found in adults. Leukemia does not have gender, race or age specific, but it has many different branches that effect different people. Everyday about 143 Americans are diagnosed with leukemia and of those about 66 people will die.
