how to prevent lung cancer, the biggest cause of lung cancer is smoking,and 90 percent of lung cancer patients are reported to have smoked. now, researchers in korea have found how lungcancer forms as a result of smoking, and they may also have found a way to prevent it.
when cancer-causing agents in cigarettes enterthe body, they stimulate calcium channels and calcium enters the cells. substances that help promote cell growth arepushed out, inducing cancer cell development. the researchers discovered that blocking thecalcium channels stops cancer cells from forming. when mice that were fed tobacco constituentwere treated with calcium channel blockers for 12 weeks, the rate of cancer cell formationwas reduced to one-tenth that of the control group. the blockers also proved effective in preventinglung cancer caused by stress. many existing blood pressure medications arebeing used to block calcium channels, but
they could also be used to prevent lung cancer. in a study of seven-point-five million patientswith hypertension, the incidence of lung cancer was reduced by about 30 percent among thosethat took drugs with calcium channel blocking effects... compared to those who did not. "based on the data for patients who took medicationsto suppress high blood pressure, we believe the medicines could be used to prevent ortreat cancer. the dosage used to treat high blood pressurecould inhibit the development of lung cancer." the researchers believe their findings willhelp those at risk for lung cancer and patients who have overcome the illness.
