GPs in England are being urged to "think again" if they see a sick patient three times and can't pin down a diagnosis, or find their symptoms are getting worse.
The new NHS initiative, called Jess's Rule, is named after Jessica Brady who contacted her GP on more than 20 occasions after starting to feel unwell in the summer of 2020.
She was told her symptoms were related to long Covid and that she was "too young for cancer". She died from advanced stage 4 cancer later that year, aged 27.
Health Secretary Wes Streeting said her death was "a preventable and unnecessary tragedy" and the rule would improve patient safety by helping GPs "catch potentially deadly illnesses".
Jessica Brady, from Stevenage, was a talented engineer at Airbus, involved in the design of satellites.
