The number of people dying from cancer each year has increased, according to the World Health Organisation’s International Agency for Research on Cancer (IARC).
The global death toll went up by 8%, increasing from 7.6 million –
calculated in a 2008 survey – to the figure of 8.2 million that was
estimated for 2012.
In respect of just actual diagnoses of
cancer, this has also increased, with over 14 million being diagnosed
with cancer in 2012. This marks a significant increase from the 12.7
million cases that were recorded in 2008.
Last year, an estimated 1.7 million women were given new a new
diagnosis of breast cancer, according to the World Health Organisation
(WHO). This represents an increase in excess of 20% from 2008, with both
incidence and mortality going up.
In fact, the disease is now the most prevalent of all cancers in women across 140 countries around the world.
Dr David Forman, from the WHO’s International Agency for Research on
Cancer, said: “Breast cancer is also a leading cause of cancer death in
the less developed countries of the world. This is partly because a
shift in lifestyles is causing an increase in incidence, and partly
because clinical advances to combat the disease are not reaching women
living in these regions.”
IARC’s report, named GLOBOCAN 2012, offers the most recent available
statistics for 28 different types of cancer within 184 countries,
providing an extensive look into the problem of cancer across the globe.
The report states that the most diagnosed cancers worldwide in both
sexes combined are lung, breast and colorectal cancers. The cancers
found to commonly result in death are lung, liver and stomach cancers.
Overall, lung cancer – primarily caused as a result of smoking – was found to be the world’s most common cancer. The 1.8 million cases recorded is 13% of the total.
The burgeoning problem of cancer is believed to be linked to a change
in lifestyles in the developing nations, shifting more closely towards
industrialised countries.
However, the report noted “huge inequalities” between rich and poor
countries. For instance, new cases of cancer being higher in developed
countries, it is the less developed countries that have much higher
death rates. Reasons for this are thought to be due to lack of screening
and access to treatment, meaning cancerous tumours often not being
found at an early enough stage.
Christopher Wild, IARC’s director, commented: “An urgent need in
cancer control today is to develop effective and affordable approaches
to the early detection, diagnosis, and treatment of breast cancer among
women living in less developed countries.”
