Health Information For Parents
Juvenile myelomonocytic leukemia (JMML) is a rare childhood cancer. It happens when immature blood cells (called blasts) make too many myelocytes and monocytes (two types of white blood cells). These myelocytes, monocytes, and blasts crowd the normal cells in the bone marrow and other organs in the body, causing the symptoms of JMML.
Juvenile myelomonocytic (mye-eh-low-mah-nuh-SIT-ik) leukemia usually happens in children younger than 4 years old.
JMML develops over time. A child may have very few symptoms at first because they can take months to develop.
A child with juvenile myelomonocytic leukemia might:
Many children diagnosed with juvenile myelomonocytic leukemia have a change in their genes (a mutation). The change happens in monocytes (MAH-nuh-sites), which are part of the immune system.
Some medical conditions — such as neurofibromatosis type 1 and Noonan syndrome — can make a child more likely to develop JMML.
Doctors use special tests when they suspect leukemia. These include:
Chemotherapy (the use of drugs to kill cancer cells) may be used to temporarily control juvenile myelomonocytic leukemia.
But the most effective treatment is a stem cell (bone marrow) transplant. To do this, doctors:
Researchers are looking into the use of alternative treatments, such as:
Having a child being treated for cancer can be stressful for any family. But you’re not alone. To find support, talk to your doctor or a hospital social worker. Many resources are available to help you get through this difficult time. You also can find information and support online at:
Leukemia refers to cancers of the white blood cells. With the proper treatment, the outlook for kids with leukemia is quite good.
While this type of blood cancer is more common in adults, it affects children, too. Thanks to advances in therapy, most kids with CML can be cured.
Acute lymphoblastic leukemia (ALL) is the most common type of childhood cancer. Because it develops and gets worse quickly, prompt treatment is very important. With treatment, most kids are cured.
Acute myeloid leukemia (AML) happens when the body makes too many immature white blood cells. Among kids with leukemia, 20% have this type. With treatment, most recover.
Stem cells help rebuild a weakened immune system. Stem cell transplants are effective treatments for a wide range of diseases, including cancer.
Anemia happens when there aren’t enough healthy red blood cells in the body. It can be caused by many things, including dietary problems, medical treatments, and inherited conditions.
From treatments and prevention to coping with the emotional aspects of cancer, the Cancer Center provides comprehensive information that parents need.
If you’ve just finished a long hospital stay, you may have questions about reconnecting with friends and family. Get answers in this article for teens.
Side effects of cancer treatment can include flu-like symptoms, hair loss, and blood clotting problems. After treatment ends, most side effects go away.
This promising new type of cancer treatment stimulates a person’s immune system so it is better able to fight disease.
Taking care of a chronically ill child is one of the most draining and difficult tasks a parent can face. But support groups, social workers, and family friends often can help.
Chemotherapy (chemo) is treatment with medicines that stop the growth of cancer cells.
Cancer is a serious illness that needs special treatment. Find out more about how kids can cope with cancer.
Chemotherapy is a big word for treatment with medicines used to help people who have cancer. This medicine kills the cancer cells that are making the person sick.
Certain cancers, or cancer treatment, can weaken the immune system, requiring a child to stay home to avoid exposure to germs. Here are ways to help your child make the best of it.
Stem cells can develop into cells with different skills, so they’re useful in treating diseases like cancer.
Visit our Cancer Center for teens to get information and advice on treating and coping with cancer.
