Howard Stern's radio sidekick Robin Quivers has confirmed she has been battling cancer.

Quivers, who is a long time regular on The Howard Stern Show, recently took some time off from her job, and she used her appearance on the airwaves on Monday (09Sep13) to reveal she has secretly been struggling with health problems.

The 61 year old admitted she has been battling cancer for a year, receiving treatment including radiation therapy and chemotherapy, but doctors have now told her she is finally cancer-free.

In the emotional segment on Stern's Sirius Xm show, the shock jock admitted he feared the worst when she initially told him the news, telling listeners, "I gotta be honest, I thought she was a goner."
