In the first study, researchers from Ohio State University discovered that a gel based on freeze-dried black raspberries helps prevent precancerous mouth tumors (lesions) from becoming malignant. "This gel appears to be a valid means of delivering anthocyanins and other cancer-preventing compounds directly to precancerous cells, since it slowed or reduced lesion progression in about two-thirds of study participants," said researcher Susan Mallery. According to the American Cancer Society, oral squamous cell carcinoma is one of the deadliest forms of cancer, causing 7,500 deaths each year in the United States. Because no chemopreventive agent or treatment method other than radical mouth surgery exists, even those who survive the cancer often emerge significantly disfigured. And even in many cases where tumors are fully removed, they still recur. "Oral cancer is a debilitating disease and there is a desperate need for early detection and management of precancerous lesions," said Mallery. Most mouth cancer begins as small, noncancerous lesions in the mouth that are difficult to detect. It was these lesions that were treated in the Ohio State University study. Researchers carried out the study on 20 participants who had identifiable precancerous mouth lesions [...]
