More needed to reduce radon-related cancer

Personal commitments needed to reduce violence.

Police patrols for alcohol-related crashes: more rigorous evaluation needed.

Driving vehicles after drinking alcohol is common, and has been shown to increase the risk of car crashes. There is a strong community perception that increased police patrols are effective in reducing dangerous driving practices such as drink– driving. A recently published review on the Cochrane Database of Systematic Reviews has examined the effectiveness of police patrols for reducing crashe...

Pancreatic cancer: are more chemotherapy and surgery needed?

Most patients diagnosed with pancreatic cancer die from the disease. Although mortality from the most common cancers has declined in the past few decades, the mortality for patients with pancreatic cancer has remained high. On the basis of rising incidence, demographic data, and survival projections, pancreatic cancer is predicted to become the second most deadly cancer in the near future. Panc...

Induced abortion and breast cancer: more scientific data are needed.

Despite intense study, the causes of breast cancer remain elusive (7). Reproductive factors are clearly of importance, but the nature of their influence on risk is complex and under continuous reassessment. It has been difficult to disentangle their effects because they are highly correlated and imperfect surrogates for unidentified underlying causal factors and because they are weakly related ...

Contribution of radon and radon daughters to respiratory cancer.

This article reviews studies on the contribution of radon and radon daughters to respiratory cancer and proposes recommendations for further research, particularly a national radon survey. The steady-state outdoor radon concentration averages 200 pCi/m3, and indoor levels are about 4 times higher. The primary source of radon in homes is the underlying soil; entry depends on multiple variables a...
