If you noticed some added rasp in Jon Hamm's voice as of late, it was no coincidence.
The Mad Men actor has a large polyp (an abnormal tissue growth) in his throat that he plans to have removed with surgery, Peopleconfirmed.
Hamm's rep says that he will have a routine outpatient procedure to remove a single polyp from his throat.
According to the American Speech-Language-Hearing Association, polyps can be caused by a variety of factors, including singing, allergies, smoking, tense muscles, talking loudly, and drinking caffeine and alcohol, which can dry out the throat and vocal cords.
Hamm recently appeared as a presenter alongside Alec Baldwin at Sunday's Emmy Awards, awarding Veep star Julia Louis-Dreyfus with the Emmy for Outstanding Lead Actress in a Comedy Series.
The 42-year-old actor, who plays the troubled advertising executive "Don Draper" on the acclaimed AMC drama, won't begin shooting Mad Men until production resumes in 2014.
