Some nurses and doctors find websites such as WebMD to be the bane of their practices, as patients will search online for hours looking to diagnose themselves, convinced they have some terrible illness.

In the case of one U.K. college student, that self-diagnosis fell on deaf ears and eventually cost the woman her life. When she was 18, Bronte Doyne went to the doctor complaining of severe stomach pains and over the next 16 months questioned whether what was first thought to be appendicitis might actually be fibrolamellar hepatocellular carcinoma, according to a June 2015 report from the Daily Telegraph.

Doyne and her family kept asking doctors to do more digging, according to a report by the Daily Beast, but the pleas appeared to fall on deaf ears until it was too late. Finally admitted to the hospital after being told by doctors to "stop Googling your symptoms," Bronte died 10 days later on March 23, 2013.

Doyne's mother, Lorraine, has taken up her daughter's crusade, according to the Daily Mail.

"Bronte was denied pain relief, referrals were hugely delayed, and efforts by her family to gather information and understand Bronte's prognosis were handled in an evasive and aloof manner," Lorraine Doyne told The Daily Mail. "Her fears that her symptoms over the preceding months were cancer-related were proved right. I want to see changes and action now."
