The World Health Organization (WHO) published on its Twitter account on Thursday a number of risks that, if avoided, can reduce cancer deaths by more than 30 percent.
Such risks included the use of tobacco, obesity, an unhealthy diet with low fruit or vegetable intake, lack of physical activity, alcohol use, sexually transmitted HPV- infection, infection by hepatitis B, ionizing and non-ionizing radiation, urban air pollution, and indoor smoke from household use of solid fuels.
"Tobacco use is the single most important risk factor for cancer causing about 20% of global cancer deaths and around 70% of global lung cancer deaths. In many low-income countries, up to 20% of cancer deaths are due to infection by HBV (hepatitis B) and HPV", the international health body said on its website.
"More than 60% of world’s total new annual cases occur in Africa, Asia, and Central and South America. These regions account for 70% of the world’s cancer deaths."
According to the WHO, the number of new cancer cases is expected to increase by about 70% over the next twenty years, stating that around 14 million new cases and 8.2 cancer related deaths occurred in 2012.
The organisation emphasised that cancer "figures among the leading causes of morbidity and mortality worldwide."
