Jon Hamm is scheduled to undergo throat surgery next week, according to new reports.

The Mad Men star allegedly has two large polyps on his vocal cords, Life & Style reported. He reportedly coughed up blood recently and finally he decided to get checked out.

Hamm's surgery is set to take place in Boston, according to the magazine's source.

"January Jones was talking about it at the 2013 Fox Emmys afterparty last night," an insider told Life & Style.

Earlier this month, The National Enquirer claimed Hamm was going under the knife.

"In the past Jon has been terrified that if he has them removed, his vocal cords could be severely damaged," a pal said. "Jon has tried to deal with the pain, but over time, he started coughing more and more often, which only aggravated his condition and made his throat feel like it was raw."

"He FREAKED out. He went to see a doctor who told him he needs to have the polyps removed as soon as possible," the insider added.

According to the Enquirer report, the polyps might be cancerous.

Dr. Jerome Spunberg, a radiation oncologist from West Palm Beach, Fla., who has not treated Hamm, said while most vocal cord polyps are benign, they "can definitely be cancerous."
