A new study finds that zinc supplements can help prevent cancer in the esophagus, as reported by Science Daily. Researchers at the University of Texas at Arlington (UTA) evaluated the reaction of human esophageal cancer cells and healthy human cells to zinc. They discovered that zinc supplements slowed down the growth of esophageal cancer cells.

Esophageal cancer ranks sixth in the leading cause of human cancer deaths worldwide, according to the National Cancer Institute (NCI). According to the American Cancer Society (ACS), approximately 16,940 people were diagnosed with esophageal cancer this year. Moreover, more or less 15,690 deaths from the cancer of the wind pipe. The average five-year survival rate of people with this type of cancer is only about 18 percent.

Results of the study showed that zinc slows down excessively active calcium signals in cancer cells. Normal cells do not have these calcium signals with increased activity, which promote cancer cell growth. Zui Pan, lead author of the study and an associate professor of nursing at UTA, concluded that “zinc selectively inhibits cancer cell growth.”
