Cancer Statistics, Facts and Figures For 2014
Update January 12, 2014 – Cancer Statistics, Facts and Figures For 2014
Cancer is one of the diseases which claim most lives on an annual basis worldwide. Since 2008, the disease has been responsible for more than 10% of all deaths worldwide (according to the World Health Organization). The most common types of cancer are lung cancer, cancers of the liver, breast, ovary and colon and these are the types which collectively cause most deaths from cancer every year. Even though the rates of mortality resulting from cancer differ between men and women, cancer remains one of the major killer diseases of both groups. In order for you appreciate this piece of information the more, some cancer facts and figures worth knowing are presented in this article.
Notable Cancer Facts and Figures
According to epidemiological studies, the cancer statistics 2011 presented slightly elevated values than the cancer statistics 2010. Due to the fact that scientists have predicted a continued sustenance of this annual slight increase, it is expected that the cancer statistics 2012 will also witness a slight increases compared to those of last year.
According to epidemiological studies, about 200,000 deaths occur annually as a result of cancers, more especially those related to the workplace. In the United States alone, one-quarter of all deaths recorder annually result from various types of cancer. Of these value, lung cancer accounts for about 30%, making it the most deadly form of cancer in the country. Prostate cancer has been found to be the common cancer in men while breast cancer is the most common form in women. The prevalence of cancer in children is much reduced compared to values in adults (150 cases/1 million children), with leukemia being the most common form of cancer in children.
In third world countries, the fraction of deaths caused by cancer is much reduced compared to the developed countries. This is due to the presence of other causes of higher death rates such as infectious diseases, injury as a result of insecurity and so on.
In Canada, cancer is the number one cause of deaths, making up about 30% of all deaths recorded in the country. Cancer is a very prevalent disease in Canada. The most common form in Canadian males is prostate cancer (28% of all new cases) while breast cancer is the most common form in females, accounting for 28% of all new cases. In general, lung cancer is the most prevalent form of cancer.
Due to the high prevalence of lung cancer, there is a need to take a brief look at some lung cancer facts and lung cancer statistics. Lung cancer affects the lungs (as the name implies) and is most prevalent among tobacco smokers.
Skin cancer, according to research studies on skin cancer facts and skin cancer statistics, is also very common due to the fact that it is most likely caused by environmental agents. The most common form of skin cancer is known as skin melanoma.
Basic Facts about Cancer
Cancer can simply be defined as an abnormal and uncontrollable growth and proliferation of cells in a tissue or organ. Cancer begins when, for reasons still unknown, a cell which used to be normal suddenly becomes abnormal in terms of its rate of growth and proliferation. It then multiplies so rapidly that much of the affected tissue or organ soon becomes almost fully (or even entirely) occupied by its daughter cells. Cancer cells may even spread out of their original location to affect neighboring tissues and organs as well.
Even though, cancer can develop in any body tissue or organ, not all cancers are life-threatening to the same degree. In other words some cancers kill faster than others. More light will be shed on this later in the article.
Even though cancer may develop in people of any age group, research has revealed that most of the cancers known are more prevalent in people who are above 50 years of age. Studies on cancer revealed that cancer gradually develops over many years and this fact has been suspected to be the reason why the disease is more prevalent in people of age 50 and above.
Causes Of Cancer
The causes of cancer continue to remain an enigma till present day. However, research, by means of epidemiological studies has been able to deduce that some lifestyle preferences and other factors such as environmental and genetic factors may increase the risk of cancer.
Carcinogens are chemical, physical, or biological agents which bring about the cellular alterations that eventually lead to cancer. They are the mostly implicated culprits as far as the issue of the likely causes of cancer is concerned. Certain everyday substances have been found out to increase the risk of cancer due to the fact that they contain carcinogens. One of the most well-known carcinogens is tobacco. It has been found out that smoking increases the risk of various cancers such as cancers of the lungs, esophagus, stomach, kidney and liver. So, the more a person’s intake of tobacco, the higher the risk of cancer. Second hand smoke or environmental tobacco smoke also has the same lethal effect. Carcinogens may also be borne in diet.
Studies on cancer have revealed eating that foods containing saturated fats such as steak, hamburger and dairy products with high fat content increases the risk of stomach cancer. Apart from carcinogens, disease-causing agents known as pathogens and exposure to radiation are other very likely causes of cancer.
Treatment Options For Cancer
This discussion on cancer facts and figures would not be complete without a brief discussion of the various methods of treating the disease.
- Surgery remains the most effective method of eliminating cancers as it entails the removal of the affected organs as a whole. However, it may be ineffective in removing microscopic extensions of the tumor which may have spread to other organs
- Radiation therapy is also used to treat cancer. This is the process through which high-energy particles such as gamma rays and X-rays are focused on a cancer-infested tissue or organ in order to destroy the cancerous cells. Many side effects are associated with this treatment procedure, one of which is the likely damage of surrounding normal body cells.
- Chemotherapy, which involves the use of drugs and hormone therapy, which involves the administration of synthetic hormones are also commonly adopted methods for the treatment of cancer.
