Well, 12000 wbc doesnot seems leukemia for sure. Actually it is a normal number.
Leukemia is a form of cancer that begins in the blood-forming cells of the bone marrow - the soft, inner part of the bones. Leukemia - which literally means "white blood" in Greek - occurs when there is an excess of abnormal white blood cells in the blood. Known as leukocytes, these cells are so plentiful in some individuals that the blood actually has a whitish tinge.
The first indications of leukemia often are nonspecific or vague. They may occur with other cancerous as well as noncancerous disorders. Although signs and symptoms vary for each type of leukemia, there are some general features. Broad symptoms of leukemia may include:
* Fatigue
* Malaise (vague feeling of bodily discomfort)
* Abnormal bleeding
* Excessive bruising
* Weakness
* Reduced exercise tolerance
* Weight loss
* Bone or joint pain
* Infection and fever
* Abdominal pain or "fullness"
* Enlarged spleen, lymph nodes, and liver
You may ask your doctor why he suspects of leukemy.
I wish you health!
