Pediatric Cancer Symptoms

Cancer in children is not common, and it can be hard to detect because symptoms are similar to many childhood illnesses.
The Pediatric Oncology Resource Center uses the acronym CHILDCANCER to describe some common symptoms of childhood cancer:
- Continued, unexplained weight loss
- Headaches, often accompanied by early morning vomiting
- Increased swelling or persistent pain in bones, joints, back, or legs
- Lump or mass, often in the abdomen, neck, chest, pelvis, or armpits
- Development of excessive bruising, bleeding, or rash
- Constant, frequent, or persistent infections
- A whitish color behind the pupil
- Nausea that persists or vomiting without nausea
- Constant tiredness or noticeable paleness
- Eye or vision changes that occur suddenly and persist
- Recurring or persistent fevers of unknown origin
Most of the time, these symptoms are caused by conditions that are not cancer, such as an injury or infection. See a doctor if your child has any of the above symptoms for a diagnosis.
