A major problem in the distribution of cancer care is the so-called 10/90 gap. The 10/90 gap refers to the finding that 90% of research investments go to just 10% of the world's population. This is because there is a big difference in the types of cancer by country that people are most at risk for, as explained in the World Cancer Report. For example, in developing countries people are at greater risk of pneumonia; breast; stomach; colorectal; and liver cancer, while developed countries often have many more cases of breast and prostate cancer. Furthermore, in developing countries 1 in 4 cancers are due to infections, while in developed countries this is only 1 in 10. All these differences make it more difficult to find a cancer treatment that works globally. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

Chinnock is a health and medical communicator, specializing primarily in global public health. He is qualified in Applied Biology and Human Nutrition. He is a specialist chief scientist, working at the Medical Research Council of South Africa and is an associate professor in the Faculty of Health Sciences, University of Cape Town. Clarke studied at the Faculty of Medicine, Dentistry and Biomedical Sciences. Their article is also very reliable as they are all experts in their field and are from different parts of the world, so they can make a good article about the developed world and the developing world. The World Health Organization (WHO) and the World Cancer Research Fund (WCRF) are both internationally recognized organizations with trusted reputations. Finally, Kavanos is not an expert in any medical field, he studied at the London School of Economics, but all his sources are very reliable, so his source is also reliable. So the 10/90 gap is largely due to differences in cancers globally. However, there is more. Many developing countries struggle to provide primary healthcare. According to Kavanos, globalization can be a factor in this sense. He explains that while this could improve economic growth in developing countries, it could also undermine investments in healthcare in individual countries. Another effect that globalization has on cancer care is that many developing countries can expect an increase in cancer cases due to globalization. This is because people age and because urbanization leads many people to a less healthy lifestyle, with less exercise, unhealthier food and greater industrial exposures. Accompanying this increased risk of contracting cancer is often late diagnosis and inadequate treatment. According to Kavanos, 80% of patients in developing countries already have an incurable form of cancer when they are diagnosed. Not only do developing countries face different risks when it comes to cancer, but they also have more difficult access to epidemiological data and research. Not to mention the untapped potential of many researchers in developing countries. Since there is often no good system for funding researchers, it is more difficult to contribute their work to national and international medicine, maintaining.
