The WHO has provided its own estimates of how non-communicable diseases are set to rise in developing countries. These authors pool data from national registries and international databases to compare data on the differing burden from individual diseases. They outline the risk factors associated with the diseases.

The main three killers are cardiovascular disease, diabetes, and cancer. The paper ranks different types of cancer by how many people in developing countries they kill (lung and breast cancer are the deadliest) and also ranks diabetes prevalence by country (India, followed by China, has the highest prevalence).

To tackle these diseases, say the authors, people need to look closely at the risk factors in their life – eating healthily and exercising can do much to reduce the chances of getting one of these diseases.
