The rate of cancer diseases in the world has increased in the last 30 years. The World Health Organization (WHO) also has announced a 13 percent increase in cancer cases in children over the past 20 years. According to a study made by International Agency for Research on Cancer (IARC) and World Health Organization (WHO), 300,000 cancer cases among children under the age of 14, were detected between 2001 and 2010. The joint work of the World Health Organization and the International Agency for Research on Cancer has been published in the Lancet, an important medical journal.
According to this report the rate of cancer incidences among children was 140 in 1 million between 2001 and 2010 whereas it increased to the rate of 124 in 1 million in the 1980s. Researchers of WHO and IARC state that genetic predisposition has been seen as the first reason of the cancer among children. Cancer types seen among children differ from the ones seen among the adults.
Leukemia is the most common species in all parts of the world. Cancers types affecting the central nervous system are mostly seen in high-income countries. Cancer types affecting the central nervous system are the second most common type in the world. The lymphoma which is mostly seen in low-income countries is in third rank in the world.
For the first time, IARC gathered cancer data on young people aged between 15 and 19. Lymphoma and melanoma are the most common cancer types seen among the youngs between 15 and 19. Researchers think environmental toxins or infections are probably increasing the risk of cancer in children and with this research they are planning to measure the effects of environmental toxins or infections.
The data for this study were collected from 62 countries which have the 10 percent of the world’s children population and from the 153 records in these regions. These records are better kept in Western countries. Records from Africa and Asia account only 5 percent of the total data. Because of lack of a conscious approach and lack of adequate equipment, many cancer cases cannot be diagnosed.
