What kind of white blood cell means you have cancer?

No type of white blood cell definitively indicates the presence of cancer. Various blood tests, including complete blood count (CBC) and differential count, can provide information about the different types of white blood cells and their levels in the body. However, a CBC alone cannot diagnose cancer.

While certain types of leukemia, a cancer of the blood and bone marrow, may show abnormal white blood cell counts or the presence of immature white blood cells called blasts, these findings require further investigation and specialized tests for proper diagnosis.

It is crucial to consult a healthcare professional and undergo appropriate medical tests and evaluations to determine the cause of any abnormal white blood cell levels or other potential signs and symptoms suggestive of cancer. Self-diagnosis based on white blood cell counts is not recommended.
