U.S.-based biotech firm Volatile Analysis‘ non-profit Hudson Alpha have developed a chewing gum that may help detect cancer. According to the company’s scientists, each type of cancer produces a unique set of chemicals known as volatile organic compound. These chemicals differ in composition per cancer type, in the same way a healthy lung produces compounds that are different from a diseased lung, the scientists explained. Researchers said the gum absorbs these volatile compounds from a person’s saliva. The chewing gum is then analyzed after 15 minutes of chewing.
