ON THIS PAGE: You will find out more about body changes and other things that can signal a problem that may need medical care. Use the menu to see other pages.

Children with ALL may experience the following symptoms or signs. Sometimes, children with ALL do not have any of these changes. Or, the cause of a symptom may be a different medical condition that is not cancer. The early signs of ALL can look very much like the flu or other common illnesses. When 1 or more of these symptoms lasts for longer than you would expect, or you are worried about a symptom or sign on this list, please talk with your child’s doctor.

  • Frequent infections

  • A fever that doesn’t go away

  • Feeling weak and tired all the time

  • Bone pain

  • Swollen lymph nodes (for example, in the neck, under the arms, or in the groin)

  • Paleness

  • Bruising or bleeding easily

  • Difficulty breathing

  • Headache

  • Enlarged liver or spleen

If you are concerned about any changes your child experiences, please talk with your child’s doctor. Your doctor will ask how long and how often your child has been experiencing the symptom(s), in addition to other questions. This is to help figure out the cause of the problem, which is called a diagnosis.

If childhood ALL is diagnosed, relieving symptoms remains an important part of cancer care and treatment. This may be called palliative care or supportive care. It is often started soon after diagnosis and continued throughout treatment. Be sure to talk with your child’s health care team about the symptoms your child experiences, including any new symptoms or a change in symptoms.
