Cancer geographically

Cancer is a major word health problem with wide geographical variations in its incidence. Out of every one million children aged 0-14 years, approximately 130 develop cancer every year. In developedcountries cancer is the leading cause of death from disease in 1-14 year olds. Approximately 67% of children can be cured if the disease is diagnosed early and appropriately treated, cancer althoughthe cure rate depends upon the specific type of cancer.
Unfortunately however, most children with cancer do not receive curative therapies becau7se they live in developing countries, the disease isusually advanced by the time of diagnosis and curative therapies are frequently unavailable. Palliation of pain and other symptoms is a component of care for all children with cancer. For somechildren, the emphasis of care may be primarily one of palliation.
During the course of their illness, almost all children with cancer experience some pain, caused either directly by the disease or b yinvasive procedures, treatments, or psychological distress. At present, there are no accurate figures on the worldwide magnitude of different types of cancer pain in children because countries differwidely in their diagnostic capabilities and reporting systems. However, rcent documentation of childhood cancer pain within specific treatment centres in developed countries indicates that all childrenwith cancer do experience pain related to their disease and/or treatment with more than 70% of them suffering from severe pain at some point. Although the means exist for its effective relief,children’s pain is often not recognized, may be inadequately treat3ed, even when sufficient resources are available.
Disease-related pain can be acute or chronic and is usually caused by direct invasion ofanatomical structures by pressure on (or entrapment of) nerves, or by obstruction. The most common childhood malignancies, such as leukaemia, lymphoma, and neuroblastoma often produce diffuse bone...
