Does a High White Blood Cell Count Mean Cancer?

Inflammatory changes in the body, sometimes shown by "inflammatory markers" in the blood such as CRP (C-reactive protein), have been linked with a number of diseases, including cancer.

Researchers have now used data from the Women's Health Initiative (WHI) Study to see if there's a relationship between the white blood cell (WBC) count and the occurrence of 4 specific cancers. Their findings are published in the Archives of Internal Medicine .

The WHI study involved over 140,000 postmenopausal women from 40 clinical centers in the USA . Women with a white blood cell count in the high-but-still-normal range (between 7 and 15 thousand per mm3) were significantly more likely to develop invasive breast cancer, colorectal cancer, endometrial (uterine) cancer , and lung cancer. They also had an increased risk of breast, lung, and overall mortality.

The actual increased risks ranged from 15% to 63% - quite small, compared with the risk linked with smoking, for instance. However, a WBC count over 7,000/mm3, if it's persistent and without a known cause, means the patient should be watched (and maybe tested) for signs of early cancer.

Considering there is a margin of error in WBC -- the presence of an appreciable increase in WBC in typically indicative of an immune system response that could be caused by many different factors, such as stress, infection, etc. Recent studies have shown that an individual's white blood count can vary between what is classfied as 'high' and what is classified as 'normal' based on being exposed to different environmental triggers (pollen, subway, public, etc.). This is a normal response of your immune system and is not normally a cause for any alarm. As always, followup with your primary care physician or seek emergency medical services if you experience any distressed symptoms.

To a cancer patient, it's the white blood cells that are the most important. When someone is originally diagnosed with cancer, their white blood cell count may be too high or too low (it depends on the type of cancer). Normal levels of white blood cell count are generally considered to be 5000 to 11,000 cells per cubic millimeter per liter. Low white blood cell count is less than 5000 cells per cubic millimeter per liter. High white blood cell count is 11,000 and above.

what does it mean when the left side under the ribs is burning hot and my white blood cell count is high. I did have melanoma. My grandmother died from melanoma. It was removed from me and it has roots with tumors on the end of its roots. I have usual scarring and brusing. shortness of breath. I sweat while I sleep and my feet and hands burn. I get very dizzy suddenly and loose my balance. headaches, swollen upper stomach, fatigued, run down. can't shut my eyes without feeling like I am going to fall.
