Triple negative breast cancer cells process tryptophan to promote survival while traveling through the body in order to seed new tumor sites, researchers say. “I’m not saying that people with metastatic breast cancer shouldn’t eat turkey during the holidays, but triple-negative breast cancer appears to have found a way to process tryptophan more quickly, equipping cancer cells to survive while in circulation, which allows them to metastasize,” says the first author of a new paper.
