The 29-year-old former Republic of Ireland international is suffering from stage one malt lymphoma.
The former Leeds United and Barnsley midfielder is hoping to return to action in January following treatment.
"Stephen McPhail has been diagnosed with a stage one malt lymphoma, previously known as a pseudo lymphoma," read a club statement.
"Treatment is expected to last for three weeks with a return to football by January 2010.
