In July, the star, 44, revealed that she found a tumor in her breast that required surgery. At the time, she was not certain of her exact diagnosis or course of treatment, but now her spokesperson said in a statement that it conflicts with the series' filming schedule.

"Maura Tierney regrets that she will not be able to continue her role on Parenthood due to a conflict with the production schedule of the show and her breast cancer treatments," her spokesperson said in a statement. "Ms. Tierney and her doctors remain confident that the outcome of her treatments will be positive. She is deeply disappointed that she will not be able to rejoin such a highly respected, talented, fun and funny group of actors and wishes to thank Jason Katims and NBC for their patience and support."
NBC said their "thoughts and best wishes" were with her.

"While we are saddened that Maura Tierney won't be able to continue in her current role in Parenthood, our main concern is for her quick and full recovery," the network said.

Parenthood, a contemporary reimagining of the 1989 comedy, had been scheduled to begin filming this summer and initial episodes were pushed back until midseason. No new air date has been set. Tierney is best known for her 10-year stint as Dr. Abby Lockhart on NBC's ER, for which she earned an Emmy nomination.
