Leider nur englisch:
http://www.dietandcancerreport.org/Es soll aber bald eine deutsche Übersetzung geben - wird angekündigt. Nur wird nicht viel drinstehen über das Gebiet, das uns hier interessiert. Ich zitiere aus dem englischen Report:
"7.18.5 Nervous system
Cancers of the brain and central nervous system are the 18th
most common type worldwide. An estimated 189 000 cases
occurred in 2002, accounting for around 2 per cent overall.
These cancers are most frequent in high-income countries,
with rates more than twice those of middle- to low-income
countries. Brain tumours are relatively common among
childhood cancers. They are the 13th most common cause
of cancer death, and are usually fatal. The overall 5-year survival
rate is less than 25 per cent, with higher rates for many
brain tumours that occur during childhood, and in highrather
than in middle- to low-income countries.2 Also see box
7.1.1.
Tumours of neural tissue account for approximately half
of these cancers, with most of these being glioblastomas.4
Meningiomas are the other major type of central nervous system
tumour, with sellar tumours, cranial and spinal nerve
tumours, central nervous system lymphomas, and other rare
brain tumour types comprising the remainder.
The incidence of these cancers appears to be increasing
worldwide, although the trend is not entirely clear.124 The
causes of brain and central nervous system cancers have not
been well established.
The narrative review did not produce any findings.
Because these cancers are uncommon, any study investigating
their possible links with food, nutrition, and physical
activity would be unlikely to be fruitful. Because they are
diverse, any investigation that grouped all of them together
would also be unlikely to show consistent results."
