Cause and effect of global cancer
Cancer is a leading cause of death globally. Three-quarter of cancer deaths occur in developingcountries or the third world (WHO, 2010). If current knowledge were put into practice, at least one third of cancer cases could be prevented, another third could be detected early, treated and cured; and suffering could be alleviated through palliative care for patients with advanced cancers. (WHO, 2009) In low- and middle-income countries, cancer overwhelmingly affects the poor. This has huge implications for human suffering, health systems, health budgets and the drive to reduce poverty. There are around 30 million new cases of cancer per year in the world. (Eduardo Cazap , 2011) Attributed to changes in risk factors, such as lifestyle trends associated with economic development and threat of cancer caused by infectious diseases, as well as changes in diet, more and more crowded living conditions and an increase in tobacco use in developing countries. (WHO, 2010)A trend is beginning to emerge in some developing countries. There is less and less physical activity in our daily lives, at work and at home, as well getting from place to place. Cancer has become more and more serious in developing countries or the third world. There arenumerous factors lead to this situation, but there are four main causes: few specialists, equipment, chronic infections and lack of awareness. The first cause is not having enough resource people, such as oncologist, cancer specialists. There are 15 Africa countries do not have possess even a single radiation therapy machine, only 20%of patients survive cancer (Margaret Chan, 2010). The second factor is that we do not have the resources to buy equipment. Such as the lack of radiation therapy machines, without budget available ministries of health. The problem is most severe in sub Saharan Africa, where 80 percent of the continent’s one billion inhabitants live without proper access to basic radiotherapy and related cancer services.(Veronica Riemer, 2010) The third issue is that chronic infections are leading risk factors for cancer in low- and middle-income countries, such as hepatitis B (HBV), hepatitis C virus (HCV) and Human Papilloma Virus (HPV). Programme on Cancer Control has focused on the needs of developing countries or the third world. (WHO-IAEA,2009) IAEA offers unparalleled expertise in radiation medicine, a vital component of cancer diagnosis and treatment. For an agency that received the Nobel Peace Prize in 2005.Later that year, the IAEA established its Programme of Action for Cancer Therapy (PACT) to help expand radiotherapy capacity in developing countries or the third world and build partnerships to deal with the huge disparities that exist in cancer care services. After that, PACT, WHO and other key international cancer organizations have undertaken increasingly productive collaboration, working together to tackle the crisis on a broad, multidisciplinary front. The fourth cause is the lack of awareness about the seriousness of the cancer threat. World Cancer Day on 4 February of each year is to have an opportunity to launch key messages to people (WHO, 2010). WHO is taking significant measures to prevent cancer and other chronic diseases. A key achievement has been the entry into force this past year of the first-ever WHO global health treaty. The WHO Framework Convention on Tobacco Control (WHO FCTC) is a major step towards the goal of reducing tobacco use, which is the leading preventable cause of cancer. To date, 121 countries have ratified the treaty (WHO, 2006).
Despite significant advances in medical science over the last 100 years, cancer remains the main cause of death. In developed countries, a number of factors lead to cancer and different regions have different leading causes.
