Researchers at the Massachusetts Institute of Technology (MIT) have developed a way to determine, by sequencing DNA of liver cells, whether those cells have been exposed to a potent carcinogen, thereby paving the way for earlier diagnosis of the deadly disease.
In many parts of the world, exposure to a fungal product called aflatoxin is believed to cause up to 80% of liver cancer cases.
This fungus is often found in corn, peanuts, and other crops that are dietary staples in those regions.
