- <p>Breathing cigarette smoke may cause cervical cancer
- </p>
- <p> Studies have long linked smoking and cancer of the cervix,
- which is expected to kill at least 6,000 women in the U.S. this
- year. Now a new study has not only confirmed the link but also
- concluded that women who breathe smoke from others' cigarettes
- -- so-called passive smoke -- are equally at risk for cervical
- cancer.
- </p>
- <p> The report, the first thorough evaluation of the effects of
- smoking on women with cervical cancer, was published last week
- in the Journal of the American Medical Association by a team of
- researchers at the University of Utah Medical School. It found
- that women who smoke are about three times as likely to develop
- cancer of the cervix as nonsmokers. But the study, which also
- sought to assess the damage done by exposure to passive smoke,
- produced a surprise: women who inhaled passive smoke for three
- or more hours a day were not only more likely to have cervical
- cancer than those who did not but were as much at risk as active
- smokers.
- </p>
- <p> In addition, the researchers found that passive smoke in
- the home was a greater risk than such smoke in other locations,
- possibly because it was more constantly present. They also
- discovered that smoking and being constantly exposed to the
- smoke of others put women at even greater risk than either
- factor separately.
- </p>
- <p> Doctors have long known about other risk factors for
- cervical cancer, including sexual activity at an early age and
- sex with multiple partners. And they have implicated some types
- of human papillomavirus (HPV), which causes genital warts, as
- the probable culprit. The University of Utah researchers,
- however, could only speculate about a possible mechanism by
- which smoking may cause cervical cancer. Harmful components of
- cigarette smoke, they suggest, may travel through the blood into
- the tissues of the cervix and somehow activate the virus.
- </p>
- <p> Others viewed the findings with caution, noting that a
- cause-and-effect relationship between passive smoking and
- cervical cancer remains to be shown. Still, declared Lawrence
- Garfinkel, an epidemiologist at the American Cancer Society,
- "cervical cancer should probably be added to the list of
- tobacco-induced cancers."
