Does cancer cause high white blood cell count?

Rarely, a high white blood cell count can be a symptom of certain blood cancers, such as acute myeloid leukemia, chronic myelogenous leukemia and chronic lymphocytic leukemia.


Does high white blood count indicate cancer?

Does a high white blood cell count indicate cancer? Not always. A high white blood cell count could signal certain types of cancer, such as leukemia or lymphoma, but it more often is a sign of inflammation or infection.

What level of white blood cells indicates cancer?

The WBC count range for people with CML is much higher than normal levels. The median WBC count among people with CML is 100,000/μl , but it can climb higher. Some sources note that people with acute or chronic leukemia may have a WBC count in the 100,000–400,000 range.


Would white blood cells be high or low with cancer?

A person with cancer can develop a low WBC count from the cancer or from treatment for the cancer. Cancer may be in the bone marrow, causing fewer neutrophils to be made. The WBC count can also go down when cancer is treated with chemotherapy drugs, which slow bone marrow production of healthy WBCs.

What is the most common reason for high white blood cell count?

Overall, the most common cause for a high white blood cell count is response to infection. Another potential cause of an elevated white blood cell count is leukemia. This is effectively a cancerous change of the blood and bone marrow which causes significant overproduction of white blood cells.


Disorders of Leukocytes/White Blood Cells - An Overview



Should I worry if my white blood count is high?

Leukocytosis is a normal immune response and isn't always a cause for concern. Most of the time, it means that your body is fighting off infection or inflammation. However, there are times when a high white blood cell count could indicate something more serious, such as leukemia.

What is an alarming WBC count?

A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should.

What bloodwork shows cancer?

What tests are done to check for cancer?
  • Complete blood count (CBC).
  • Tumor markers.
  • Blood protein testing.
  • Circulating tumor cell tests.


What blood test results indicate cancer?

Higher-than-normal numbers of lymphocytes or monocytes can indicate the possibility of certain types of cancers. Some cancers and their treatments may cause neutropenia. Neutropenia is when a person has low numbers of neutrophils. This increases the chance of getting a bacterial infection.

What blood test shows cancer?

Tumor marker tests use a sample of blood to look for chemicals made by cancer cells. These tests don't always help with diagnosing cancer because many healthy cells also make these chemicals. And some conditions that aren't cancer can cause high levels of tumor markers.

What diseases does a high white blood cell count indicate?

A high white blood count may mean you have one of the following conditions:
  • A bacterial or viral infection.
  • An inflammatory disease such as rheumatoid arthritis.
  • An allergy.
  • Leukemia or Hodgkin disease.
  • Tissue damage from a burn injury or surgery.


What are the first signs of having leukemia?

Common leukemia signs and symptoms include:
  • Fever or chills.
  • Persistent fatigue, weakness.
  • Frequent or severe infections.
  • Losing weight without trying.
  • Swollen lymph nodes, enlarged liver or spleen.
  • Easy bleeding or bruising.
  • Recurrent nosebleeds.
  • Tiny red spots in your skin (petechiae)


Will cancer show up in routine bloodwork?

Aside from leukemia, a broad term for cancers of the blood cells, most cancers cannot be detected during routine blood work. However, blood tests can provide helpful information about: Overall health. Organ function.

What treatment if white blood cells are high?

Leukapheresis is a way of removing abnormal white blood cells from the blood. You might have this treatment if you have a very high white blood cell count. Very high numbers of leukaemia cells in the blood can cause problems with normal circulation.


Can stress cause high white blood cell count?

Stress levels increase white blood cell count

This indicates a connection between elevated stress levels and the body's production of what are known as inflammatory leukocytes, a particular variety of white blood cell. Normally, inflammatory leukocytes are the body's defense system against infection and disease.

How do you feel when your white blood count is high?

A high white blood cell count alone doesn't cause any symptoms. The symptoms you feel may come from the medical problem that your white blood cells are fighting. For example, if you have pneumonia, you may have a fever and trouble breathing. These are symptoms of pneumonia, not of a high white blood cell count.

Does high white blood count mean leukemia?

While having an elevated or abnormally high white blood cell count does not necessarily indicate leukemia, the source of the condition will need to be identified if it is found to exceed the levels and duration of a normal immune response to an infection.


Can a CBC pick up cancer?

A CBC can detect blood cancers like leukemia, Hodgkin lymphomaNon-Hodgkin lymphomaand multiple myeloma. However, it cannot give you a definitive answer as to whether you have other types of cancer, though results may provide clues that bear investigation.

Does a normal CBC rule out cancer?

Blood counts alone can't determine whether you have a blood cancer, but they can alert your doctor if further testing is needed. A complete blood count (CBC) is the number and types of cells circulating in your blood. Your CBC is measured using laboratory tests that require a small blood sample.

When should you suspect leukemia?

"A patient may be tested for leukemia if he or she has unexplained weight loss, night sweats or fatigue, or if he or she bruises or bleeds easily," Dr. Siddon says. "Sometimes routine blood work shows an unexplained elevated number of white blood cells."


At what age is leukemia usually diagnosed?

The median age of a patient diagnosed with acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) or chronic myeloid leukemia (CML) is 65 years and older. However, most cases of acute lymphocytic leukemia (ALL) occur in people under 20 years old. The median age of an ALL patient at diagnosis is 15.

Where does leukemia usually begin?

Leukemia starts in the soft, inner part of the bones (bone marrow), but often moves quickly into the blood. It can then spread to other parts of the body, such as the lymph nodes, spleen, liver, central nervous system and other organs.

What does a CBC look like with leukemia?

Understanding your blood count test results

If you have leukemia, your blood cells count will likely show higher than usual levels of white blood cells, which include leukemic cells. You may also have lower than usual red blood cell and platelet cell counts.


What triggers leukemia in adults?

While the exact cause of leukemia—or any cancer, for that matter—is unknown, there are several risk factors that have been identified, such as radiation exposure, previous cancer treatment and being over the age of 65.

How do you rule out leukemia?

By looking at a sample of your blood, your doctor can determine if you have abnormal levels of red or white blood cells or platelets — which may suggest leukemia. A blood test may also show the presence of leukemia cells, though not all types of leukemia cause the leukemia cells to circulate in the blood.
