SYMPTOMS OF CHILDHOOD CANCER!!!!!!!!!!!!!

• vomiting that persists for more than 7 days and is worse when your child wakes up in the morning, wakes your child up at night, or is associated with a headache. For children with common headaches, a red flag that it might be something more serious than a simple migraine would be if the headaches continued to get worse over time, becoming either more severe or more frequent. Brain tumors might also cause other neurological symptoms, such as trouble walking, seizures or sudden changes in their personality. 
• bone pain or muscle pain that doesn't follow a known injury and doesn't improve in a few weeks. These types of pain are different than the usual 'growing pains' that children get at night, which usually doesn't cause pain in a specific spot, is helped by massage, doesn't limit your child's activities, and tends to be chronic (occurring on and off for months or years). Also remember that chronic back pain is not very common in younger children and can be a sign of a spinal cord tumor
• a persistent cough or trouble breathing that doesn't respond to usual treatments for infections or asthma.
• an enlarging mass, whether it is in the abdomen, neck, arms or legs.
