John Hart, spokesman for Coburn, told reporters he expects the senator "to be back as soon as he is able, hopefully next week."

Coburn had surgery to treat prostate cancer in 2011, and has also survived melanoma and colon cancer.

The senator missed Monday night's procedural vote on the Employment Non-Discrimination Act and will miss work for the rest of the week, according to Politico.
