Saying the past few weeks have been difficult for Christina Applegate would be putting things mildly.

In early June, an ex-boyfriend of the Samantha Who? star was found dead after an apparent drug overdose. Now we’re learning that the actress has just been diagnosed with breast cancer. Coincidentally (?), Applegate was recently announced as a participant of next month’s Stand Up 2 Cancer telethon.

Today, the 36-year-old’s rep confirmed the medical report to the media:

“Christina Applegate was diagnosed with an early form of breast cancer. Benefiting 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. No further statement will be issued at this time.”

No announcement has been made so far as to how this may affect production on Applegate’s ABC comedy. Samantha is currently scheduled to return on October 6.
