Simple Saliva Test Could Improve Lung Cancer Detection

continued...

In an earlier epidemiological study, Fujiki and colleagues suggested that drinking more than 10 small servings of green tea a day (800 milliliters, or 27 ounces) protected against lung, colorectal, liver, and stomach cancers.

Though attempts to find better screening methods and cancer prevention agents may eventually help reduce lung cancer deaths, Edelman counters that the best way to reduce mortality from the disease is to convince people to stop smoking.

"You have to remember that at least 85% of lung cancer cases are preventable," he says. "It would be very shortsighted for us as a country to put huge amounts of money into screening at the expense of programs to prevent smoking. We make that point over and over again. But we don't want people to become complacent and think that it is OK to smoke because we will be able to find the cancer early and cure it."
