Margot got the news in her early 20s: "You have liver cancer," her doctors told her. Specifically, Margot had a form of liver cancer known as fibrolamellar carcinoma, a diagnosis with deadly prospects. More than three times as many people battle liver cancer in the U.S. today, compared to 1980, and more than twice as many die from it, according to the American Cancer Society. "In large part, the increase in metabolic syndrome is why we're seeing the sharp increase in liver cancer," Baretti says. Liver cancer currently ranks as the sixth-deadliest cancer in the country, behind cancers of the lungs, colon and rectum, pancreas, breasts, and prostate, according to the National Cancer Institute.
