Jed Wheatley, 33, from Longton, Stoke-on-Trent, was jailed for 27 months after telling the courts his mum had died of the disease.
The 33-year-old first made the claim that his mum was battling cancer to a probation officer in a bid to be treated more leniently by the courts.
Stoke-on-Trent Live reported he made the claim after being given a suspended sentence for robbery in 2016.
As a result of his claims Wheatley was allowed to skip supervision appointments and unpaid work so he could travel to Coventry “to care for her”.
But in 2018 he went one step further and said his mum had died.
This then became part of his barrister’s mitigation plea when he was sentenced for an assault on a man following a sexual encounter between them.
Wheatley has now been prosecuted for perverting the course of justice after the court received information his mum was alive and well and his lies unravelled.
He was jailed for 27 months yesterday while his mum watched from the public gallery.
Prosecutor Richard McConaghy said Wheatley was handed an 18 month jail sentence – suspended for two years – on December 23, 2016, for a robbery and was then allocated a probation officer.
Mr McConaghy said: “On April 25, 2017 he told the officer his mother was suffering from cancer and he was having to make regular visits to see her in Coventry.
“That was a lie. His mother did not have cancer. She had cancer a number of years previously but she had been well for some time.
“He was to repeat that lie in supervision appointments in June 2017 and January 2018.
“He was allowed a significant degree of latitude.
“On February 21, 2018 he took matters one step further when he told his officer his mother had died and it had an adverse effect on his mental health. He claimed he was self-harming and abusing alcohol and drugs.”
The court heard that Wheatley committed battery in November 2017 and was sentenced on April 13, 2018, to a community order with 60 hours unpaid work and a rehabilitation activity requirement for 20 days.
Mr McConaghy said: “His counsel, acting on instructions, put forward that the defendant’s mother had been gravely ill in November 2017, the time of the battery, and he had been going to Coventry to assist with her care. He reiterated she had died.”
But a week later, the defendant reported to his probation officer that his ex-girlfriend saying he he had made up his mother’s death and he had received threats on Facebook.
Mr McConaghy added: “What he was doing was laying the groundwork for wriggling out of his lie.”
Judge Paul Glenn said to Wheatley: “Your conduct came to light after the court received information that the mitigation submitted by counsel on your behalf on April 13, 2018 was untrue.
“Your mother had in the past suffered from cancer but makes it plain she has been clear of that for five years or more.
“You lied to your probation officer that your mother was ill, suffering from cancer and you were regularly visiting her. You were given an enormous amount of latitude regarding appointments for supervision and unpaid work.
“On February 21, 2018 you told the officer your mother had died.
“I take a very serious view of perverting the course of justice. This was not a spur of the moment decision. You are manipulative, you are cunning.
“These were calculated actions of someone who is totally dishonest. You lied to a probation officer and continued with that lie to deceive the court.
“The lie you chose to tell was despicable, contemptible. Frankly it beggars belief. The assertions you made were truly shocking.
“It strikes at the heart of the criminal justice system and it must be deterred.”
