Although it is unlikely that your child will develop cancer, as a parent, you need to be aware of the symptoms of childhood cancer. Observe your child for any sudden, persistent changes in health or behavior as listed above. Since most of the symptoms of cancer can also be attributed to benign conditions, the diagnosis of cancer can be a long process. You must trust your own instinct and work as a team with your doctor, using your knowledge of your child and your doctor's knowledge of medicine to protect your child's health.
