The Aging Populations Worldwide is leading to an Unprecedented Increase in Cancer Cases and Fatalities
The aging populations worldwide are leading to an unprecedented increase in cancer cases and fatalities. Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph system. Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancer is named for the organ or type of cell in which they start – for example, Cancer that begins in the colon is ...view middle of the document...
However, sometimes this orderly process goes wrong. The genetic material (DNA) of a cell can become damaged or changed, producing mutations that affect cell growth and division. When this happens, cells do not die when they should and new cells form when the body does not need them. The extra cells may form a mass of tissue called tumor.
Numbers in cancer cases according to estimates from the International Agency for Research on Cancer (IARC), there were 12.7 million new cancer cases in 2008 worldwide of which 5.6 million occurred in economically developed countries and 7.1 million in economically developing countries. The corresponding estimates for total cancer deaths in 2008 where 7.6 million (about 21,000 cancer deaths a day), 2.8 million in economically developed countries and 4.8 million in economically developing countries. The estimated future burden could be much higher than given above due to the adoption of Western lifestyle, such as smoking, poor diet, physical inactivity, and reproductive factors, in economically developing countries .
By 2030, the global burden is expected to grow to 21.4 million new cases and 13.2 million cancer deaths simply due to the growth and aging of the population, as well as reductions in childhood mortality and deaths from infectious diseases in developing countries. Cancers related to these factors, such as lung, breast, and colorectal cancers, are increasing in economically transitioning countries....
