Cancer Will Kill 10 Million People This Year – International Agency For Research On Cancer Report Says

It’s a matter of fact that cancer is still consider as one of the major death causing disease that can be so dangerous that it’s presence is going to last so long until death occurs beside all curing techniques. It wouldn’t be a surprise if we come to know that millions of people this year are going to die due to this cancer.

 

Recently, International Agency For Research On Cancer reveals the data and reports that shows that more than 9.5 million deaths are going to happen this year due to cancer and this may exceed if not controlled.One in five men and one in six women around the world develop cancer during their lifetime, according to the latest figures from the from the International Agency for Research on Cancer (IARC). One in eight men and one in 11 women die from the disease.

The rising toll of cancer is clear from the latest global estimates which predict there will be 18.1 million new cases this year and 9.6 million deaths. Four years ago, when the IARC last did the same exercise, there were 14.1 million cases and 8.2 million deaths.

In more affluent parts of the world with good healthcare systems, it is preventable cancers with causes rooted in our lifestyles and modern culture that dominate. Most lung cancers are caused by smoking, while the causes of breast cancer include obesity and alcohol.

 

Global Cancer Burden

The global cancer burden is estimated to have risen to 18.1 million new cases and 9.6 million deaths in
2018. One in 5 men and one in 6 women worldwide develop cancer during their lifetime, and one in 8 men
and one in 11 women die from the disease. Worldwide, the total number of people who are alive within
5 years of a cancer diagnosis, called the 5-year prevalence, is estimated to be 43.8 million.

The increasing cancer burden is due to several factors, including population growth and ageing as well as
the changing prevalence of certain causes of cancer linked to social and economic development. This is
particularly true in rapidly growing economies, where a shift is observed from cancers related to poverty
and infections to cancers associated with lifestyles more typical of industrialized countries.

Effective prevention efforts may explain the observed decrease in incidence rates for some cancers, such
as lung cancer (e.g. in men in Northern Europe and North America) and cervical cancer (e.g. in most
regions apart from Sub-Saharan Africa). However, the new data show that most countries are still faced
with an increase in the absolute number of cases being diagnosed and requiring treatment and care.

Global patterns show that for men and women combined, nearly half of the new cases and more than half
of the cancer deaths worldwide in 2018 are estimated to occur in Asia, in part because the region has
nearly 60% of the global population.

Europe accounts for 23.4% of the global cancer cases and 20.3% of the cancer deaths, although it has
only 9.0% of the global population. The Americas have 13.3% of the global population and account for
21.0% of incidence and 14.4% of mortality worldwide.

In contrast to other world regions, the proportions of
cancer deaths in Asia and in Africa (57.3% and 7.3%, respectively) are higher than the proportions of
incident cases (48.4% and 5.8%, respectively), because these regions have a higher frequency of certain cancer types associated with poorer prognosis and higher mortality rates, in addition to limited access to
timely diagnosis and treatment in many countries.

Major Cancer Types in 2018

Cancers of the lung, female breast, and colorectum are the top three cancer types in terms of incidence,
and are ranked within the top five in terms of mortality (first, fifth, and second, respectively). Together,
these three cancer types are responsible for one third of the cancer incidence and mortality burden
worldwide.

Cancers of the lung and female breast are the leading types worldwide in terms of the number of new
cases; for each of these types, approximately 2.1 million diagnoses are estimated in 2018, contributing
about 11.6% of the total cancer incidence burden. Colorectal cancer (1.8 million cases, 10.2% of the total)
is the third most commonly diagnosed cancer, prostate cancer is the fourth (1.3 million cases, 7.1%), and
stomach cancer is the fifth (1.0 million cases, 5.7%).

Lung cancer is also responsible for the largest number of deaths (1.8 million deaths, 18.4% of the total),
because of the poor prognosis for this cancer worldwide, followed by colorectal cancer (881 000 deaths,
9.2%), stomach cancer (783 000 deaths, 8.2%), and liver cancer (782 000 deaths, 8.2%). Female breast
cancer ranks as the fifth leading cause of death (627 000 deaths, 6.6%) because the prognosis is
relatively favourable, at least in more developed countries.

Global Patterns By Level Of Human Development

For many cancers, overall incidence rates in countries with high or very high HDI1 are generally 2–3 times
those in countries with low or medium HDI. However, the differences in mortality rates between these two
categories of countries are smaller, on the one hand because lower-HDI countries have a higher
frequency of certain cancer types associated with poorer survival, and on the other hand because access
to timely diagnosis and effective treatment is less common. In men, lung cancer ranks first and prostate
cancer second in incidence in both developed and developing countries. In women, incidence rates for
breast cancer far exceed those for other cancers in both developed and developing countries, followed by
colorectal cancer in developed countries and cervical cancer in developing countries.

Global Cancer Patterns By Sex

Lung cancer is the most commonly diagnosed cancer in men (14.5% of the total cases in men and 8.4% in
women) and the leading cause of cancer death in men (22.0%, i.e. about one in 5 of all cancer deaths). In
men, this is followed by prostate cancer (13.5%) and colorectal cancer (10.9%) for incidence and liver
cancer (10.2%) and stomach cancer (9.5%) for mortality. Breast cancer is the most commonly diagnosed
cancer in women (24.2%, i.e. about one in 4 of all new cancer cases diagnosed in women worldwide are
breast cancer), and the cancer is the most common in 154 of the 185 countries included in GLOBOCAN 2018. Breast cancer is also the leading cause of cancer death in women (15.0%), followed by lung cancer
(13.8%) and colorectal cancer (9.5%), which are also the third and second most common types of cancer,
respectively; cervical cancer ranks fourth for both incidence (6.6%) and mortality (7.5%).

 

Worrying Rise In Lung Cancer In Women

Lung cancer is a leading cause of death in both men and women and is the leading cause of cancer death
in women in 28 countries. The highest incidence rates in women are seen in North America, Northern and
Western Europe (notably in Denmark and The Netherlands), China, and Australia and New Zealand, with
Hungary topping the list.


“Best practice measures embedded in the WHO Framework Convention on Tobacco Control have
effectively reduced active smoking and prevented involuntary exposure to tobacco smoke in many
countries,” says Dr Freddie Bray, Head of the Section of Cancer Surveillance at IARC. “However, given
that the tobacco epidemic is at different stages in different regions and in men and women, the results
highlight the need to continue to put in place targeted and effective tobacco control policies in every
country of the world.”
“These new figures highlight that much remains to be done to address the alarming rise in the cancer
burden globally and that prevention has a key role to play,” says IARC Director Dr Christopher Wild.
“Efficient prevention and early detection policies must be implemented urgently to complement treatments
in order to control this devastating disease across the world.”
