Cancer: Main Cause of Death Within Rich Countries


In accordance with two landmark global surveys over a period of 10 years, the results revealed that cancer is now the main cause of death within rich countries.

However, worldwide, heart disease still causes the most deaths among middle-aged people and according to data, it accounts for over 40% of mortalities

17.7 million deaths

During 2017, as per opinion it was responsible for approximately 17.7 million deaths.

The twin studies which was published in The Lancet, a medical journal, disclosed that now more people are dying from cancer than heart disease, in more prosperous countries.

Emeritus professor Gilles Deganais, associated with Qubec’s Laval University stated, the world is recently observing an epidemiologic changeover among the various categories where non-communicable illnesses are concerned, as cardiovascular disease is not the main cause of mortality in the richer countries.

He added his team’s research revealed that cancer was in the 2nd place, as the universal cause of death across the globe during 2017. It accounts for more than 26% of all mortalities.

Deganais stated as the rates of heart disease came down on a worldwide basis, cancer might become the principal cause of within a couple of decades.

The research followed over 160,000 adults in countries varying in all the income groups for 10 years. The results disclosed that people living in the poorer nations, have a 2.5 higher chance to succumb from heart disease than their richer counterparts.


The study likewise found that diseases like pneumonia and cancer, which is non-infectious were more common in richer states, compared to low-income states.

A second Canadian study observed data, derived from patients in the 21 identical countries; it was discovered that what is known as ‘modifiable risk factors’ were responsible for 70% of all heart disease on a worldwide basis.


These include: socioeconomic & behavioral factors and diet.


High cholesterol, diabetes or obesity, which are metabolic risk factors, were responsible for over 40% of heart disease, whilst by far the most prominent determinant of disease within the richer nations.


A strong link was found in developing countries between heart disease and poor diet, household air pollution as well as low education levels.

Salim Yusuf

Professor of medicine, Salim Yusuf, associated with the McMaster University said a change in approach is needed to alleviate the immeasurably high effect of cardiovascular disease within countries with a low- & middle-income.


He added that these countries’ governments should start to invest a larger portion of their GDP to prevent and manage non-communicable illnesses which include cardiovascular disease, instead of focusing on infectious diseases.
