WASHINGTON (CNN) -- White House Press Secretary Tony Snow revealed to CNN he plans to return to his post next week, a month after a cancerous growth was found on his liver.

"I'm expecting to be back Monday," Snow said in a telephone interview, adding that he only needs one final sign-off from his doctor.

Snow said he is scheduled to start chemotherapy next Friday and will "dial back" on his workload if the treatments get difficult. But Snow said he's confident he can balance everything because he withstood six months of chemotherapy after he was first diagnosed with colon cancer in 2005 -- and at the time was still able to work six days a week as a commentator for Fox News radio and television.

The White House announced March 27 that Snow's cancer had returned and spread to his liver and elsewhere in his body, which elevated White House Deputy Press Secretary Dana Perino into Snow's job on an acting basis.

While White House aides expected Snow's recovery to take longer, the press secretary said he "healed up" from last month's abdominal surgery sooner than expected and is eager to get back to work, though he's not exactly sure when he will back on camera in the White House briefing room.

"I will try to do the briefing [Monday]," he said, adding that it will depend upon how quickly he gets back up to speed.
