Your child has been diagnosed with acute lymphoblastic leukemia (ALL). It is a common type of childhood cancer that is often curable with treatment. ALL is also called acute lymphocytic leukemia. Your child’s health care team will help you as you make important decisions regarding your child’s health. Read on to learn more about ALL and how it is treated.
ALL is a fast-growing cancer that affects bone marrow (the spongy inside of bones) and blood. The blood is made up of three main types of cells:
White blood cells fight infection.
Red blood cells carry oxygen throughout the body, which gives a person energy.
Platelets help the blood to clot, which helps stop bleeding when a person is cut.
ALL affects the white blood cells. When a person is healthy, white blood cells form in the bone marrow. With ALL, large numbers of abnormal white blood cells called leukemic blasts are produced. Leukemic blasts outlive and crowd out healthy cells. As time goes on, there are more blasts than healthy cells, so that the blood can’t do its job. This leads to problems, such as infections and bleeding. Anemia can also occur. This is a condition in which the blood doesn’t have enough red blood cells.
ALL is the most common type of childhood cancer. ALL is not contagious, meaning your child can’t pass it to another person.
ALL occurs when a certain type of white blood cell called lymphocytes grows abnormally (mutate). What causes this to happen is not fully known. Mutations in certain genes may affect the way your child’s cells grow. This gene mutation is random and couldn’t have been prevented. In rare cases, other factors, such as exposure to certain viruses, chemicals, or radiation, play a role. But most often, the cause of leukemia in children is unknown.
Some common symptoms of ALL include fever, pale skin, tiredness (fatigue), and weakness. Your child may have experienced some of these symptoms, or other symptoms.
Your child’s health care provider examines your child. You will be asked about your child’s health history. Your child may also have one or more of the following:
Blood tests to take samples of blood and examine them under a microscope
Imaging tests, such as a chest X-ray, to take detailed images of areas inside the body
Bone marrow aspiration and biopsy to take a sample of bone marrow from the hipbone
Lumbar puncture, also called spinal tap, to take a sample of the fluid that surrounds the spinal cord from the child’s lower back
Chemotherapy (“chemo”) is the main treatment used for ALL. It destroys cancer cells with powerful cancer-fighting medications. Your child may receive a combination of chemo medications. They may be given by mouth, injection, or through a tube (IV) that’s usually put into a vein in the arm or chest. Your child’s health care provider can tell you more.
The goal of supportive treatments is to protect the child from infection, prevent discomfort, and bring the body’s blood counts to a healthy range. During your child’s treatment, he or she may be given antibiotics. These are medications that help prevent and fight infection. Anti-nausea and other medications may also be given. These help ease side effects caused by chemotherapy. Your child may receive a blood transfusion to restore the blood cells destroyed by treatment. Blood is taken from a donor and stored until the child is ready to receive it.
With treatment, ALL is often curable. But chemotherapy and radiation may cause some problems, such as damage to certain organs. So your child’s health will need to be monitored for life. This may include clinic visits, blood tests, and ultrasounds of the heart.
This includes any of the following:
In an infant under 3 months old, a temperature of 100.4°F (38.0°C) or higher
In a child 3 to 36 months, a temperature of 102°F (39.0°C) or higher
In a child of any age who has a temperture of 103°F (39.4°C) or higher
A fever that lasts more than 24-hours in a child under 2 years old, or for 3 days in a child 2 years or older
Your child has had a seizure caused by the fever
Pain that can’t be controlled
Uncontrolled nausea or vomiting
Receiving a cancer diagnosis for your child is scary and confusing. It’s important to remember that you are not alone. Your child’s health care team will work with you and your child throughout your child’s illness and care. You may also wish to seek information and support for yourself. Doing so can help you cope with the changes cancer brings. Learning about and talking with others who also have a child with cancer may help you and your family cope. Some helpful resources include:
