Swollen glands and weight loss are early symptoms of childhood cancer, says expert

The most common childhood cancers are leukaemia, brain and other central nervous system tumours, and lymphoma. These cancers account for more than half of all cancers diagnosed in children but only a small percentage of these cancers are diagnosed in adults. Although a small number of cases of childhood cancers are due to genetic abnormalities, the causes of most childhood cancers are unknown, says Manoj Kumar, consultant paediatrician, KIMS ICON Hospital.
