The most important aim of the World Cancer Day campaign is to help the early diagnosis of childhood cancer. The earlier this disease gets diagnosed, the higher will be the survival chance. Non-Hodgkin lymphoma is one of the common childhood cancers. Do refer to a physician when you notice one of these symptoms in a child around you: coughing; wheezing; night sweats; trouble swallowing. Keep in mind that these symptoms do not necessarily mean that a child has cancer; however, refer to a physician as soon as you notice any of them. Early diagnosis is the key to early treatment for this disease.
