WORLD: CANCER RISKS DEPEND ON LIFESTYLE

Article Abstract:

Findings in the New England Journal of Medicine reveal that whilst genetic factors do play a part in cancers, the most significant factor is the environment that people live in. The research provides a corrective balance against those who argue that heredity is a key determinant of cancer. The research, which involved studying the records of 90,000 identical and non-identical twins (45,000 pairs) living in Scandinavia, found that even if one twin had cancer the chances of the other one developing it was generally less than 15%. Of the 10,000 who had cancer predominantly in the stomach, prostate, lung, bowel and breast regions, in all cases, with the exception of prostate cancer, environmental effects accounted for a minimum of 65% of the risk.

WORLD: RISE IN NUMBER OF PEOPLE WITH HIV

Article Abstract:

It is projected that by end-2000, 36.1mn people worldwide will be living with HIV, compared with 34.3mn in 1999, with 5.3mn new infections reported for the year. The joint United Nations Aids programme estimates that in Central Asia and Eastern Europe, 0.7mn people are HIV positive, up from 0.42mn the year before. Russia especially is counting the cost of government neglect, with over 0.3mn HIV cases according to estimates, compared with 0.13mn previously. The programme's chief, Peter Piot, says that of all the infectious diseases, Aids now claims the most lives and because it claims a wide range of people is now impacting the economy and society.

The young survivors

Article Abstract:

Chemotherapy has had a significant impact on reducing childhood deaths from cancer in the UK. Many childhood cancers respond well to chemotherapy because they are different from adult cancers. In many children, the cancer takes the form of an embryonal tumour, the cells of which are easier to destroy than adult cancer cells. Researchers are now looking at the impact of chemotherapy in later life, especially on fertility, growth, hormone production and heart and lung function.
