Below The World Health Organisation (W.H.O.) summarise what we know about cancer from scientific research:
Cancer is largely preventable: by stopping smoking, providing healthy food and avoiding exposure to carcinogens. Some of most frequent cancer types are curable by surgery, chemotherapy or radiotherapy. The chance of cure increases substantially if cancer is detected early. Quality of life of cancer patients and their families can be greatly improved by provision of palliative care. Cancer control is a public health approach aimed at reducing causes and consequences of cancer by translating our knowledge into practice.
Recommendations from World Health Organisation concerning cancer include action in following areas:
· minimising or eliminating exposure to cancer causes · reducing individual susceptibility to effects of these causes · serving greatest public health potential · identifying most cost-effective long-term cancer control · tobacco control · obesity control · control of composition of diet · control of consumption of alcoholic beverages
The World Health Organisation sees cancer prevention programmes as part of integrated, national strategies. The risks they identify for cancer above are common to all noncommunicable diseases including heart, diabetes and respiratory problems. Prevention programmes for all chronic diseases are able to use same surveillance and health promotion techniques. According to WHO recognised causes of cancer include:
· occupational and environmental exposure to a number of chemicals · links between a number of infections and certain types of cancer · parasitic infection schistosomiasis · exposure to some forms of ionising radiation · excessive ultraviolet radiation
