Cancer from Germs

<p>A stomach bug is linked to gastric tumors and ulcers
</p>
<p>By Andrew Purvis
</p>
<p> Could cancer be an infectious disease? In some cases the
answer is at least partly yes. Viruses are thought to play a
role in liver and uterine cancer and some forms of lymphoma. Now
comes the news that bacteria may actually be a major culprit in
the world's second most common malignancy: stomach cancer,
which afflicts an estimated 700,000 a year worldwide.
</p>
<p> In separate studies of 130,000 and 6,000 people, reported
in the New England Journal of Medicine, researchers from
Stanford and Kuakini Medical Center in Honolulu found that
people infected with the bacterium Helicobacter pylori were
three to six times as likely to develop stomach cancer over a
20-year period as those who were not infected. "This is not just
a little risk we're talking about," says Stanford's Julie
Parsonnet, though she points out that not everyone infected with
the bacterium develops cancer. Indeed, the bug, which may enter
the body through dirty water or human contact, is extremely
common: it is present in the gut of 50% of Americans and of up
to 90% of people in poorer regions of Asia and Latin America.
Researchers believe chronic inflammation, caused by the
bacterium, combines with other risk factors, including a salty
diet low in fresh fruit and vegetables, to cause the cancer.
</p>
<p> The nefarious H. pylori has also been linked to ulcers and
gastritis--inflammation of the stomach lining. Parsonnet and
others believe that people with chronic duodenal ulcers should
consider a course of antibiotics to knock out the bug rather
than rely on costly medications like Tagamet and Zantac, which
treat the symptoms, not the cause. Meanwhile, studies are under
way in Colombia and Mexico to determine if a similar strategy
of antibiotics could play a role in cutting the world's
incidence of stomach cancer.
