    In many parts of the world, including Southeast Asia and sub-Saharan Africa, exposure to a fungal product called aflatoxin is believed to cause up to 80 percent of liver cancer cases. This fungus is often found in corn, peanuts, and other crops that are dietary staples in those regions.

    MIT researchers have now developed a way to determine, by sequencing DNA of liver cells, whether those cells have been exposed to aflatoxin. This profile of mutations could be used to predict whether someone has a high risk of developing liver cancer, potentially many years before tumors actually appear.
