Corrective rape The goal of this rapist is to humiliatedebase and hurt their victim; they express their contempt for their victim through physical violence and profane language. For these rapists, sex is a weapon to defile and degrade the victim, rape constitutes the ultimate expression of their anger.
But after decades of research, figuring out how many people might contract cancer because of them remains an elusive goal. More than 60 percent of U. But what about the rest? A report by the President's Cancer Panelreleased earlier this month, reignited a year-old controversy among cancer experts and environmental epidemiologists about how large a role environmental factors play in the No.
But scientists most likely will never be able to tease out the true role of environmental contaminants because environmental exposures, genetics and lifestyle seem to all intertwine. Ted Schettler, director of the Science and Environmental Health Networka nonprofit group that advocates use of science in setting environmental policy.
From the womb to old age, Factors and contributors essay around the world are exposed to countless carcinogens in their food, air, water and consumer goods.
The highest exposures occur in an occupational setting, but there are environmental exposures as well.
For example, benzenea known cause of human leukemia, is a common pollutant in vehicle exhaust. Radon, a natural radioactive gas found in many homes, raises the risk of lung cancer. Arseniclinked to skin, liver, bladder and lung cancer, contaminates some drinking water supplies.
Other known human carcinogens include asbestos, hexavalent chromium, aflatoxins and vinyl chloride. Sinceagencies and institutes have cited the same estimate when regulating carcinogens in the workplace, air, water and consumer products.
Roughly four percent of cancer deaths — or 20, deaths per year - may be attributable to occupational exposures, and two percent — or 10, deaths per year — to environmental exposures.

But many environmental epidemiologists say quibbling over the numbers becomes a diversionary tactic. If there are things we can move on, let's work on those.
Every year, about 1. Experts agree that most cancers are caused by lifestyle factors such as smoking, diet and alcohol. Smoking alone accounts for at least 30 percent of all U. A report by two scientists, Sir Richard Doll and Sir Richard Peto, published in the Journal of the National Cancer Institute, estimated that two percent of cancer deaths were attributable to exposures to pollutants in the environment and four percent to exposures in occupational settings.
Inthose percentages amounted to about 30, U. The report only considered deaths, not cancer cases. About half of those diagnosed with cancer die.
Also, the study only included Caucasians under the age of 65, although many cancers increase with age and many minority groups are more highly exposed to environmental contaminants. The old two percent estimate for environmentally induced cancers is still commonly used — despite advances in modern cancer biology.
New areas of cancer research are focusing on the potential for pollutants to interact with one another and with genetic factors. Carcinogens can act by damaging DNA, disrupting hormonesinflaming tissues, or switching genes on or off.
Also, exposure to hormonally active agents during critical periods of human development — particularly in the womb or during childhood — may trigger cancer later in life.The Biopsychosocial approach integrates biological, psychological, and social-cultural factors.
The levels of analysis differ but compliment one another at the same time. Alone these levels of analysis won’t show the whole picture. But together they offer a more complete understanding.
For example, alcoholism can be explained using each of the three levels of analysis but [ ].

It means that employees are dissatisfied about their jobs not because of the absence of the factors that they consider to be satisfying in their jobs.
