Between anti-vaxxers and the internet rumor mills, a UK charity has decided to fight back against "fake news" by appointing a full time nurse to respond to questions and concerns with accurate information.

Macmillan says 40 percent of cancer patients follow-up their diagnoses by turning to the internet for more information.  Sometimes, those people are left more bewildered than they were before because of unverified sites, or worse yet they try bogus treatments.

Glasgow-based nurse Ellen McPake says Macmillan asked her to "make sure people affected by cancer have a real person they can turn to online for information about their symptoms, cancer diagnosis and treatment".

Some of the rumors and hoaxes McPake will be slaying include unfounded claims that baking soda cures cancer (false!), cancer is caused by a fungus or an "acidic" diet (false!), or that chemotherapy does more harm than cancer (really, really, really egregiously false!).
