The 38-year-old Australian comedian, who is best known for his roles in television shows such as The Gruen Transfer and The Glass House, said that he was diagnosed with osteoarthritis last year during a compulsory medical check for TV employer The ABC.
According to the Herald Sun, Anderson announced while on stage at the Melbourne International Comedy Festival on Wednesday night (April 4) that he will require surgery within the next five years.
Anderson said that he had suffered from horrific back pain for years and said of the diagnosis: "My first reaction was, 'I can never go on The Amazing Race'."
Anderson caused controversy during the 2010 Logie Awards when he posted derogatory comments about stars such as Matt Preston, John Mayer and Gabriella Cilmi during the broadcast.
As a result of him and other stars posts, Twitter was banned from the 2011 Logies, but is reportedly being allowed at this year's event.
He later started tweeting about politician Tony Abbott, accusing him of being a "liar", and joked about teenage round-the-world sailor Jessica Watson.
