Christina Applegate is undergoing treatment for breast cancer, but the disease was caught early and the actress is expected to fully recover, her publicist said.
The Emmy winner's cancer was detected through an MRI ordered by a doctor and is not life-threatening, publicist Ame Van Iden said in a statement Saturday.
Applegate is scheduled to appear on a one-hour television special, "Stand Up to Cancer," to be aired on ABC, CBS and NBC on Sept. 5 to raise funds for cancer research.
The 36-year-old actress has been nominated for an Emmy and a Golden Globe for the show "Samantha Who?" in which she plays a woman who wakes from a coma with no memory of who she is.
