Actress Christina Applegate reportedly is undergoing treatment for breast cancer.

The syndicated television newsmagazine "Extra" says a representative released a statement yesterday saying: "Christina Applegate was diagnosed with an early form of breast cancer. Benefitting from early detection through a doctor ordered MRI, the cancer is not life threatening. Christina is following the recommended treatment of her doctors and will have a full recovery."

A message left with Applegate's publicist was not immediately returned.

The 36-year-old actress has earned Emmy and Golden Globe nominations for her role in ABC's comedy "Samantha Who?" She is also known for playing ditzy teenager Kelly Bundy on "Married ... with Children."
