On 29 August 2013, Yanit was banned from athletic competition for two years following a failed doping test in February 2013. After IAAF appealed the length of the ban to the Court of Arbitration for sport, her ban was extended for a further year. Yanıt first came to international prominence in 2007, winning the 100m hurdles at the 2007 European Under 23 Athletics Championships.

In 2013 the Turkish Athletics Federation announced that Yanit had failed a doping test, after traces of testosterone and the anabolic steroid Stanozolol were found in a testing sample. On 29 August 2013, a two-year ban was handed down by the Turkish Federation, precluding Yanit from competition until 5 August 2015.
Following IAAF"s appeal to the Court of Arbitration for sport, her ban was extended to 3 years for aggravating circumstances.
