CBC Test for Cancer

Last updated on October 20th, 2022 at 07:53 am

CBC test for cancer! CBC is a blood test that helps detect certain types of cancers. It can help to check for leukemia, lymphoma, myeloma, multiple myeloma, and Hodgkin’s disease.

Does a CBC Test for Cancer?

A complete blood count (CBC) is a common blood test that your doctor may recommend to;

  • Help diagnose some blood cancers, such as leukaemia and lymphoma
  • Find out if cancer has spread to the bone marrow
  • See how a person’s body is handling cancer treatment
  • Diagnose other, noncancerous conditions

If you are receiving chemotherapy, your doctor will probably watch your blood cell counts often using a CBC test.

What does a CBC test for cancer measure?

A CBC test for cancer measures the amount of 3 types of cells in your blood:

  • White blood cell count. A white blood cell count, also called a leukocyte count, measures the total number of white blood cells in a sample of blood. These cells protect the body from infection by attacking invading bacteria, viruses, and other foreign materials in the body. Some white blood cells can also attack cancer cells.
  • White blood cell differential. A white blood cell differential measures the number of each type of white blood cell. There are 5 major types of white blood cells, and each type plays a different role in protecting the body. Your doctor can learn valuable information about your health by measuring the levels of these cells:
    • Neutrophils
    • Lymphocytes
    • Monocytes
    • Eosinophils
    • Basophils
  • Red blood cell count. Red blood cells carry oxygen throughout your body. A red blood cell count, also called an erythrocyte count, measures the number of red blood cells in a sample of blood. There are several ways to measure red blood cells. Two of the most common are:
    • Hematocrit (Hct), the percentage of your blood that comprises red blood cells
    • Haemoglobin (Hgb), the amount of the protein in red blood cells that carries oxygen
  • Platelet count. A platelet count measures the number of platelets in a sample of blood. Platelets help to stop bleeding by forming blood clots.

The amounts of each of these types of cells have a normal range. Your pathology laboratory team will note this range on your CBC test lab results. A range is used instead of a specific number because a normal amount is different for each person.

What does CBC test for cancer result mean?

Your doctor and laboratory team must carefully read CBC test results. Keep in mind that many factors, including noncancerous conditions, can lead to results that fall out of the normal range. Ask your doctor to help you understand what your results mean.

  • Low white blood cell count. Some cancer treatments, mainly chemotherapy, may lower your body’s white blood cells. Cancers that affect the blood and bone marrow can also lower the count. These types of cancers include leukaemia, lymphoma, and multiple myeloma.
  • Amounts of different white blood cells. Higher-than-normal numbers of lymphocytes or monocytes can show 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. Your doctor may lower your chemotherapy dose to lower your chance of developing neutropenia. Your doctor may also recommend medication, such as white blood cell growth factors, to increase your body’s production of neutrophils, especially if you develop a fever.
  • Low red blood cell count. Some cancer treatments, mainly chemotherapy and radiation therapy, may lower your red blood cells count. This condition is known as anaemia. Blood loss, either from surgery or specific cancers, and cancers that directly involve the bone marrow can also cause or worsen anaemia. People whose red blood cell count falls too low may need a blood transfusion or medication to help bring it up.
  • Low platelet count. Some cancer treatments, such as chemotherapy or radiation therapy, may cause a decrease in platelets. Cancers that directly involve the bone marrow can also lower the platelet count. An unusually low number of platelets is called thrombocytopenia. People with low platelet levels have a greater risk of serious bleeding or bruising. If your platelet count falls very low levels, your doctor may recommend platelet transfusions.
