Cassandra Grant, aged 35, who admitted four counts of fraud, also used the names of cancer patients to receive £11,500 (€14,200) worth of hospital treatment for conditions she did not have.
Bristol Crown Court heard Grant, of Stoke Bishop, Bristol, befriended one woman with terminal bowel cancer on Facebook and pretended to have the same disease.
Grant then stole the woman’s identity and used it to admit herself to Musgrove Park Hospital in Taunton, Somerset, where she received £4,830 of inpatient treatment.
When the real patient, Carly Groombridge, became suspicious, Grant used her details to cancel one of her cancer scans.
Grant had previously admitted herself to Royal Devon and Exeter hospital under the name of a Carly Hinton with terminal bowel cancer and received £1,080 of treatment.
On another occasion, Grant attended Royal Shrewsbury Hospital using her own name and claimed to have conditions including lupus and bowel cancer.
She was given £5,500 worth of care at medical centres on the Isle of Wight after pretending to be a Louise Lett, a cystic fibrosis patient she had befriended on Facebook.
The court heard Grant also stole the identity of Clare Arrowsmith, a qualified GP , and used her credentials to gain work at Jhoots Pharmacy in Filton, Bristol in July 2013.
Judge Michael Harington sentenced Grant to 12 months imprisonment, suspended for two years after hearing how her offending was driven by a mental disorder.
“You have caused people a lot grief as a result of your behaviour,” the judge said.
“I accept that it is in large part behaviour caused by your medical psychological problems.
“It is essential that you keep receiving treatment until you put that in the past.”
Grant’s deception began in December 2012, when she admitted herself to a Nottingham hospital as Molly Davies, who required treatment for various illnesses.
