Girl has cancer. Girl goes into remission. Girl believes her cancer is back after Googling her symptoms. Girl tells doctors. Doctors ignore Girl. Girl dies from cancer.
Unfortunately, this is not an allegory. This actually happened to Bronte Doyne, a 19-year-old from England. She was suffering from fibrolamellar hepatocellular carcinoma, a rare liver cancer that only affects 200 people each year. She had first been hospitalized in 2011 when doctors suspected appendicitis. Unfortunately, that was not the only time they were wrong. Bronte was eventually diagnosed with cancer, and was told that her chances of survival were high following surgical intervention.
