Dr. Keith Roach: Antacid-cancer link may not be what you think

Dear Dr. Roach: Is it true that someone who takes antacids every day is more likely to get cancer of the esophagus?
— D.R.
A: Yes, people who take antacids frequently are more likely to be diagnosed with esophageal and stomach cancer. However, people who take more antacids usually do so because they have reflux. Reflux predisposes one to Barrett’s esophagus, which predisposes one to cancer; this is a more reasonable explanation than that taking antacids causes cancer. Although some authorities have postulated that antacids may allow bile to reflux into the lower esophagus, increasing cancer risk, I believe the primary issue is that people take antacids too long before seeking medical attention when there might be something seriously wrong.
With either possibility, the message is clear: Don’t take antacids for prolonged periods without seeing your doctor. Those symptoms might be more serious than you think.
