St. Clair County Judge Daniel Kelly exceeded the guidelines, saying it would be a "travesty of justice" to sentence Sara Ylen to less.
In December, Ylen, 38, was convicted of making up a story about two men attacking her at her Lexington home, 80 miles northeast of Detroit. The jury also convicted her of tampering with evidence by using makeup to create what looked like bruises.
Ylen's integrity has been shattered after years of being considered a sympathetic figure in eastern Michigan.
She accepted thousands of dollars from supporters and was treated by a hospice service for two years after claiming to have end-stage cervical cancer that had spread throughout her body. But state police found no evidence confirming a cancer diagnosis, and Ylen on Monday pleaded no contest to fraud in Sanilac County.
