Cancer Kills Over 20000 People A Day Says Global Report



Published: Tuesday 18 December 2007

A new global cancer report by a leading US health organization estimates
that cancer will kill 7.6 million people worldwide this year (about 20,000 cancer deaths a day), and more than 12 million people will find out they
have the disease.



5-YEAR CANCER SURVIVAL RATE FOR CHEMOTHERAPY IS 2.1%



The report is called the Global Cancer Facts and Figures
2007, and is published by the American
Cancer Society.
Using data from the Globocan 2002 database compiled
by the International Agency for Research
on Cancer (IARC), report co-author, Dr Ahmedin Jemal,
an epidemiologist with the American
Cancer Society, and colleagues, showed there were
significant disparities in the cancer rates
between the
developed and the developing world. 

Jemal and colleagues estimate that 5.4 million cancers and 2.9 million cancer related
deaths will 
 be in economically developed countries, while in the less developed world
there will be 6.7 million 
cases and 4.7 million deaths.

Infection appears to play a greater part in cancer incidence in the developing world
(26 per cent 
of all cancers) where the incidence of infection-related cancer is some
3 times higher than in 
the developed world (8 per cent of all cancers).

Also, in the less developed nations, among men, the most commonly diagnosed
cancers are 
those of the stomach, lungs, and liver, and for women, breast, cervical
and 
stomach cancer were the most commonly diagnosed.

In the developed nations, among men, prostate, lung, and colorectal cancers are
the most 
commonly diagnosed, and for women it is breast, colorectal, and lung cancers.

In the developing world, infection with the Helicobacter pylori (H. pylori) bacteria is
considered 
to be the main cause of stomach cancer; infection by the human papillomavirus
(HPV) is thought 
to be the main risk factor for cervical cancer; and hepatitis B and
C infections, which the report 
describes as rampant in Africa and East Asia, are thought
to be the main link to 
liver cancer.

Jemal and colleagues said lack of prevention, early detection and treatment facilities
were probably 
the reason for the less developed world having lower cancer survival rates. 

As an example they cited the 5-year survival rate for children with cancer, which is about
75 per 
cent in Europe and North America, but only 48 to 62 per cent in Central America.
This was also based on the IARC figures.
The report estimates that if the growing use of tobacco products persists in developing 
countries,  there will be 2 billion smokers in the world by 2030.
In 2000 there were 5 million deaths linked to smoking, of which 1.42 were from cancer, 
said the report.

According to the World Health Organization (WHO), over 80 per cent of the 1.3 billion
smokers in 
 the world live in developing countries.

There are 350 million smokers in China alone, more than the whole of the US population.

Overall, tobacco was responsible for around 100 million deaths worldwide in the 20th
century, 
and will be responsible for more than 1 billion deaths worldwide in the 21st century,
said 
the report authors. Most of the deaths will be in the developing world, and the authors
said 
stopping the rapid spread of tobacco in developing countries should be a top global
health priority.

The cancer burden is on the rise said Jemal, because developing nations are increasingly
adopting 
a western lifestyle, characterized by "cigarette smoking, higher consumption of
saturated fat and 
calorie-dense foods, and reduced physical activity".
