Evangelist and Christian singer Carman Licciardello notified fans on Facebook Thursday he's suffered a setback in his battle against cancer.
In February, doctors diagnosed the 57-year-old singer with myeloma, giving him three to four years to live. He underwent an in-depth medical evaluation in early March and began treatment then.
"Today is a bad day," Licciardello wrote, after being admitted to the emergency room with severe dehydration.
He asked his fans to pray.
"This is a war I'm fighting on a daily basis, and I might be trying too hard. I don't know," he wrote. "But as of right now, this is not good. Not good at all. Please pray. You all are my lifeline to the other side of this horrible journey."
"We've come this far -- God can't allow this testimony of his blessing to stop now. It just can't happen," he continued. "I may feel like I'm losing control, but God hasn't."
Carman has been in the throes of his first U.S. tour in 13 years. For dates and more information, visit his website or Facebook page.
