Cases
of brain cancers figures show a big difference between developing
countries and developed (LDCs have fewer cases of brain tumors),
countries - and this can be interpreted that the deaths caused by
undiagnosed tumor (patients in cases of extreme poverty do not get
diagnosed, simply because they can not access
to modern diagnostic facilities necessary for the diagnosis of a brain
tumor) and deaths from other causes linked to poverty, which precede the
onset of tumors. However, studies suggest that certain forms of primary brain tumors are more prevalent among certain groups of the population. Studies
have shown occurrence of tumors of the central nervous system in the
United States, Israel, and Scandinavia is relatively high, while Japan
and Asian countries have lower rates. These differences may reflect some biological differences as well as differences in the diagnosis of patients and reporting. Data
worldwide Ballasabh related to cancer can be found in the (WHO) World
Health Organization and handled by the (IARC International Agency for
Research on Cancer), located in France
United States of America
For
the United States in 2005, it was expected that there will be 43,800
new cases of brain tumors, which accounted for less than 1 percent of
all cancers, and 2.4 percent of all cancer deaths, and 20-25 percent of
cancers children. ,
Estimates indicate that there are 13,000 deaths annually in the United
States alone as a result of brain tumors UK tumors of the brain, the
central nervous system or other tumors inside the skull is the ninth
most common in the United Kingdom cancers (was diagnosed about 9,400
people in 2011), this is the eighth most common causes of cancer deaths (about 5,200 people died in 2012).
