Researchers have found that metals present in tobacco smoke mimic the effects of estrogens and activate the body?s estrogen receptor, an action that may increase the risk of breast cancer. These metals are a new class of potent environmental estrogens called metalloestrogens, and smoking is a significant route of exposure.
The Canadian Minister of Health, Tony Clement, announced that proposed regulations to prohibit the use of “light” and “mild” terms were pre-published in Canada Gazette, Part I on August 4, 2007, for a 75 day comment period.
Women who have migraine headaches with visual symptoms (or aura) may be at increased risk for stroke compared to women who do not have migraines, researchers reported in Stroke: Journal of the American Heart Association. The risk association between stroke and migraines also increases when other factors are added, such as recent onset of these headaches, smoking and oral contraceptive use.
In this first-of-its kind-study, researchers found that 23 percent of 3,552 hospital-based physicians surveyed were smokers, substantially higher than in the United States (3.3 percent), where the smoking prevalence in the general population is 20.9 percent, and the United Kingdom (6.8 percent), with 25 percent prevalence in the general population.
It may not be inhaled into the lungs, but smokeless tobacco exposes users to some of the same potent carcinogens as cigarettes. In the August issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, researchers at the University of Minnesota Cancer Center report that users of smokeless tobacco are exposed to higher amounts of tobacco-specific nitrosamines — molecules that are known to be carcinogenic — than smokers.
New statistics from Cancer Research UK reveal steep rises in cancers linked to excessive sun exposure, alcohol, smoking and obesity.
The National Institute of Neurological Disorders and Stroke (NINDS), a component of the National Institutes of Health (NIH), announced the launch of a new community education program, which broadens the Institute?s national stroke education campaign Know Stroke. Know the Signs. Act in Time. to promote stroke awareness among Hispanics in the United States.
In the August 7, 2007, issue of PLoS One, researchers show how a poorly understood and previously unsuspected mechanism may be the key to understanding how life-style associated forms of oxidative stress, such as exposure to cigarette smoke, damage cells in the lungs.
The long-term risk of suicide is tripled for women who have undergone cosmetic breast implant surgery, concludes a study in the August Annals of Plastic Surgery, published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. This long-term study further confirms the link between breast implants and a strikingly high risk of suicide and other related causes of death.
Women who undergo breast augmentation surgery are nearly three times as likely to commit suicide, according to a study published in the August issue of Annals of Plastic Surgery. This research confirms previously seen links between breast implants and a strikingly high risk of suicide, as well as deaths from alcohol or drug dependence.
