Leukemia is a cancer of the blood and bone marrow. It affects white blood cells. These abnormal cells can go through the bloodstream and crowd out normal blood cells in the bone marrow.
There are two main types of leukemia. The first type is the fast growing kind called acute leukemia. The second kind is slow growing and called chronic leukemia. Most childhood cases are the fast growing kind of leukemia.
The sooner cancer is found and treated, the better your child’s chances for recovery. However, even advanced cancer can usually be treated. Treatment may slow or stop the growth of the cancer and ease symptoms for a time. Ask your healthcare provider what you can expect with the type of cancer that your child has.
What is the cause?
The cancer starts in the bone marrow. Marrow is the soft, fatty tissue inside hard bone. The marrow is where blood cells are formed.
White blood cells help fight off infection.
Red blood cells carry oxygen and nutrition to your child’s body.
Platelets help blood clot.
With leukemia, your child’s body makes too many abnormal cells that crowd out other, normal blood cells.
The abnormal white cells cannot fight infections.
Fewer red blood cells make your child tired and weak.
Fewer platelets cause your child to bleed easily.
The cancer can also spread to other parts of your child’s body.
The exact cause of leukemia is not known. Having a parent, brother, or sister with leukemia increases the risk. High levels of radiation or certain chemicals may result in changes to the genes in the blood cells and increase the risk.
What are the symptoms?
Your child may have no symptoms or just mild symptoms at first. The symptoms slowly get worse. Symptoms may include:
Easy bruising or bleeding
Bone or joint pain
Swollen lymph nodes in the neck, underarms, stomach, and groin
Feeling weak and tired all the time
Loss of appetite
How is it diagnosed?
Your child’s healthcare provider will do a physical exam and ask about your childâ€™s medical history, including symptoms and possible risk factors. Possible tests include:
A bone marrow biopsy, which uses a needle passed through the skin into the bone marrow to take a small sample of tissue for testing
When the blood and bone marrow tests confirm a diagnosis of leukemia, more tests may be done before your child starts treatment to see if the cancer has spread. Tests that may be done include:
X-rays of the lungs and chest
Lumbar puncture (also called a spinal tap), which is taking a small sample of fluid from the spine with a needle to check for spread of the cancer to the brain and spinal cord
CT scan, which uses X-rays and a computer to show detailed pictures of the organs and lymph nodes
How is it treated?
You and your healthcare provider will discuss possible treatments for your child. You may also talk with a cancer specialist. Some things to think about when making treatment decisions are:
Your child’s age
Your child’s overall health
The stage of the cancer (how advanced the cancer is)
Whether the cancer has spread to other parts of your child’s body, such as the brain
Possible treatments include:
Chemotherapy (anticancer drugs), which uses medicine to kill cancer cells
Stem cell or bone marrow transplant, which uses your child’s own cells or cells from a donor
Biological therapy, which uses medicines to help your childâ€™s immune system fight the cancer
Radiation therapy, which uses high-energy X-rays to kill cancer cells
Your child’s treatment will also include:
Controlling pain or other symptoms
Controlling the side effects from treatments
Helping your child and your family cope with cancer
Often, more than 1 type of treatment is used. Your child will need to have regular follow-up visits with his or her healthcare provider.
Ask your healthcare provider about clinical trials that might be available to your child. Clinical trials are research studies to find effective cancer treatments. Itâ€™s always your choice whether your child takes part in one or not.
How can I take care of my child?
If your child has been diagnosed with leukemia:
Talk about your childâ€™s cancer and treatment options with your healthcare provider. Make sure you understand your choices.
Follow the full course of treatment prescribed by your healthcare provider.
Ask your healthcare provider:
How and when you will hear your childâ€™s test results
How long it will take your child to recover
What activities your child should avoid and when your child can return to normal activities
How to take care of your child at home
What symptoms or problems you should watch for and what to do if your child has them
Make sure you know when your child should come back for a checkup.
It may also help if your child:
Eats a healthy diet and gets regular exercise as recommended by your healthcare provider.
Gets plenty of rest.
Takes time for activities that he enjoys. Tells you or your provider if treatment causes discomfort. Usually there are ways to help your child be more comfortable.
Counseling and support groups can help children and parents cope with the situation and help the family adjust to the changes in their lives.
What can be done to help prevent the cancer from spreading or coming back?
Your child should:
Complete the full course of surgery, radiation, or chemotherapy treatments ordered by your healthcare provider.
Have regular checkups.
See a healthcare provider right away if there is a return of any previous symptoms, or if new symptoms develop.
