Every year across the world 8.2 million people die of cancer.

The fact that two-thirds of these deaths occur in low and middle income countries, and that more than 50 per cent deaths could have been prevented, is a cause for reflection and action, said World Health Organization Regional Office for South-East Asia, which also includes Nepal.

According to a press release issued by WHO regional director for Southeast Asia on the eve of World Cancer Day, tobacco use – in both smoke and smokeless forms – accounts for 22 per cent of cancer deaths globally, and is a leading cause of the disease in the Southeast Asia region.

Alcohol use, unhealthy diet and physical inactivity also contribute to the burden that has profoundly negative social, economic and developmental implications. The choices we make significantly affect the risk of cancer.

The theme of World Cancer Day (2016-2018) is ?We can. I can? to address these issues, to raise awareness about the disease.

 In the Southeast Asia region, occupational hazards and exposure to environmental substances continue to be a source of cancer and premature death. Whether through laboring in fields without adequate sun protection or exposure to cancer-causing chemicals at a factory, workers throughout the region are exposed to risks.

Outdoor air pollution, meanwhile, increases the risk of cancer for us all. The region has 14 of the world?s top 20 polluted cities, making clear the need for governments to tackle the issue with a sense of urgency. Chronic infections caused by Human papillomavirus (HPV), hepatitis B and C viruses, and Helicobacter pylori are also highly prevalent in the region and important causes of preventable cancers.

Increasing awareness means supporting healthy workplaces encouraging people to get regular check-ups for early detection of cancerous cells for improved chances of recovery and encouraging people to abstain from tobacco use, avoid alcohol and unhealthy foods, and exercise regularly.

We need to improve access to cancer treatment and services.
