World Cancer Day 2011: New physical activity guidance can help prevent breast, colon cancers4 February, 2011 | Geneva, Lyon -- The world can do more to stop people suffering and dying from cancer, such as embracing measures, including new physical activity guidance, that can prevent one-third of the annual 7.6 million cancer deaths,1 as well as providing better services for early detection and treatment of cancer.
"Physical activity has a strong role to play in reducing the incidence of certain cancers," says Dr Ala Alwan, WHO's Assistant Director-General for Noncommunicable Diseases and Mental Health. "Physical inactivity is the fourth leading risk factor for all global deaths, with 31% of the world's population not physically active."
For example, at least 150 minutes of moderate intensity aerobic physical activity throughout the week for all people aged 18 and over can reduce the risk of NCDs. For 5-17 year-olds, at least 60 minutes of moderate to vigorous intensity physical activity can protect their health and, in turn, prevent the development of NCDs.
Physical inactivity is also increasing in many countries and has major implications for health and the prevalence of NCDs, such as causing:
- 3.2 million deaths per year, including 2.6 million in low- and middle-income countries.
- Over 670,000 premature deaths (people aged under 60 years).
- Around 30% of diabetes and ischaemic heart disease.
World Cancer Day, initiated in 2005 by the Union for International Cancer Control (UICC), is a key opportunity to highlight the importance of the 19-20 September, 2011, United Nations General Assembly High-level Meeting on the Prevention and Control of cancers and the three other deadliest types of NCDs (cardiovascular diseases, chronic respiratory diseases and diabetes). These four NCDs cause more than 60% of all global deaths, equivalent to more than 35 million annually.
Dr Eduardo Cazap, President of the UICC, says: "The UN NCDs summit is a historic opportunity to establish governmental commitment towards implementing programs which will prevent millions of people suffering and dying from cancer and other chronic diseases. NCDs are dramatically increasing, particularly in developing countries where nearly 80% of deaths occur. Sadly, changing ways of life, such as reduced physical activity, are making people unhealthier and, in turn, prone to such diseases as cancer,"
One area the international community must place extra attention is in the area of research into the causes of cancer. The International Agency for Research on Cancer (IARC), the specialized cancer agency of WHO, is leading efforts into studying cancer risk factors, including physical inactivity.
Professor Chris Wild, Director of IARC, says: "Physical inactivity is one risk factor for noncommunicable diseases which can be modified and therefore is of great potential public health significance. Changing the level of physical activity raises challenges, for the individual but also at societal level, that are now important to address."
Worldwide, lung, breast, stomach, liver and colorectal cancers cause the most cancer deaths each year. The majority of all cancer deaths occurred in less developed regions in 2008 and this is expected to increase in coming decades without action.
Global Recommendations on Physical Activity for Health:
Notes for the editor:
- Cancer is the second leading cause of death worldwide after cardiovascular diseases. Knowledge about the causes of cancer, and interventions to prevent and manage the disease is extensive. Cancer can be reduced and controlled by implementing evidence-based strategies for cancer prevention, early detection and management of patients with cancer.
- Risk factors for cancer include tobacco use, chronic infections with viruses hepatitis B (liver cancer) and human papilloma (cervical cancer), being overweight or obese, radiation, some dietary factors, physical inactivity, harmful use of alcohol, some occupational exposures and various environmental chemicals.
- Prevention strategies exist to avoid risk factors, including the 2008-2013 Action Plan for the Global Strategy for the Prevention and Control of Noncommunicable Diseases. Other related strategies include the Global Recommendations on Physical Activity for Health, the Framework Convention on Tobacco Control, the Global Strategy to Reduce the Harmful use of Alcohol, and the Global Strategy on Diet, Physical Activity and Health.
- Other prevention strategies include vaccination against human papilloma virus (HPV) and hepatitis B virus (HBV), which are major causes of cervical and liver cancer respectively; control of occupational and environmental hazards and avoidance of excessive exposure to sunlight.
The International Agency for Research on Cancer (IARC) is part of the World Health Organization. Its mission is to coordinate and conduct research on the causes of human cancer, the mechanisms of carcinogenesis, and to develop scientific strategies for cancer control. The Agency is involved in both epidemiological and laboratory research and disseminates scientific information through publications, meetings, courses, and fellowships.
