Certain types of cancer cause very high death rates in the US and all over the world. Lung cancer, which is strongly linked to tobacco use, is so far the deadliest of all cancers. Reduce your chances of developing cancer by leading a healthy lifestyle.

We all know that cancer is a leading cause of deaths throughout the world. In spite of all available research and technology, mankind still has to beat a few types of cancer that continue to cause millions of deaths annually.

Cancer is a condition characterized mainly by the uncontrolled growth, proliferation, and spread of abnormal cells. Death usually results from the uncontrolled spread of these abnormal cells, leading to complications. The disease is usually detected many years after one is exposed to certain risk factors that may consist of internal (within the individual) or external (environmental) factors.

Cancer Facts and Statistics

According to the World Health Organization, more than 8 million people died of cancer in 2012.

It estimates that new cancer cases will increase from 14 million in 2012 to 22 million within the next twenty years.

WHO also reports that most new cases of cancer (60%) and cancer deaths (70%) occur in Asia, Africa, Central America, and South America. Each year, the leading causes of deaths from cancer worldwide involve lung, liver, stomach, colorectal and breast cancers.

In the USA, cancer ranks next to heart disease as a leading cause of death.

It is estimated that more than 500,000 Americans will die of the disease in 2014, and about 1.6 million new cases will be diagnosed.

The most common types of cancer in the US are breast cancer, prostate cancer and lung cancer.

Deadliest Cancers

The deadliest cancers in worldwide statistics (2012) are:

  • lung cancer (1.59M deaths)

  • liver cancer (745,000 deaths)

  • stomach cancer (723,000 deaths)

  • colorectal cancer (694,000 deaths)

  • breast cancer (521,000 deaths)

  • esophageal cancer (400,000 deaths)

In the USA, the American Cancer Society reports that the most number of deaths due to cancer (2010) are caused by:

  • lung and bronchus cancer (159,000 deaths)

  • colon cancer (50,000 deaths)

  • breast cancer (40,000 deaths)

  • pancreatic cancer (39,000 deaths)

  • prostate cancer (29,000 deaths)

Lung cancer remains to be the deadliest cancer for both men and women. However, the incidence rates (number of new cases being diagnosed) has been decreasing since the 80s in men and in the 2000s in women. Death rates have also continued to decline in recent years.

It may be a bit comforting to note that the number of deaths from cancer is declining over the years. The number of people surviving the disease for at least five years from the time they are diagnosed (5-year survival rate) is also increasing. This may reflect the progress medicine has attained in diagnosing cancers at their early stages and in treating them. However, survival rates vary greatly according to the type of cancer and the stage when they are diagnosed.

Experts believe that the key to reducing one's risk of developing cancer is to avoid exposure to potential external factors that have been found to be associated with the disease. Studies suggest that more than a third of cancer deaths may be prevented by living a healthy lifestyle. Internal factors associated with cancer, such as age, sex, racial characteristics, and genetics cannot be modified, but we can reduce our chances of acquiring the disease by knowing more about what we can do to avoid it.
