Cancer may become the leading cause of death by 2020

The Centers for Disease Control (CDC) looked at data for the five leading causes of death (heart disease, cancer, stroke, chronic lower respiratory diseases, and accidents) which together account for 63 percent of all deaths in the United States,. 

They used mortality data, population estimates and projections to estimate and predict heart disease and cancer deaths from 1969 through 2020.

The report indicates that fewer people died prematurely from cancer, stroke and heart disease between 2010 and 2014.

They predicted that from 1969 through 2020, the number of heart disease deaths would decrease 21.3% among men and 13.4% among women while the number of cancer deaths would increase 91.1% among men and 101.1% among women. They suggest that cancer would become the leading cause of death around 2016.

In 2014, more than 614,000 Americans died of heart disease and approximately 592,000 died of cancer that year.  However, in 2016, almost 601,000 Americans may die as a result of cancer, while more than 597,000 may die from heart disease.  Thus cancer could surpass heart disease as the leading cause of death among Americans this year, according to the report.

The authors conclude that the risk of death declined more steeply for heart disease than cancer over the past 4 decades. If current trends continue, cancer will become the leading cause of death by 2020.
