Jennifer Aniston was visibly moved as she listened to breast cancer survivors share their stories.
The 42-year-old was touring a new US centre which will open next week.
Lending her support to Breast Cancer Awareness month, the Hollywood star joined the wife of the vice president, Jill Biden, to visit the Inova Breast Care Centre in Alexandria, Virginia.
Jennifer was also hosting a screening of the Lifetime movie Five, an anthology of five short films about the impact of the disease.
The Friends star, together with Demi Moore and Alicia Keys, have directed one of the short films.
Jill Biden has been involved in breast cancer awareness for nearly 20 years.
She started a programme in Delaware to educate high school girls about early detection.
