in July, after being diagnosed with breast cancer. The surgery was a success, and Applegate, 36, says she's cancer free.
Applegate subsequently appeared on the Sept. 5 Stand Up to Cancer
telethon, and is expected to present
at the Primetime Emmy Awards on Sept. 21. She is also nominated as lead actress in a comedy series. Samantha Who?
's second season premieres on Oct. 13.
