Sarah Michelle Gellar is in awe of her friend Shannen Dohertys strength in the face of cancer.

Doherty, 52, has been living with stage 4 breast cancer since 2020. She was initially diagnosed in 2015 and went into remission in 2017 after undergoing a mastectomy, chemotherapy and radiation.

The actor shared an emotional Instagram update in June saying that the disease has spread to her brain.

Gellar told Access Hollywood in an interview published Wednesday that the Beverly Hills, 90210 alum is the definition of resilience.

When they say a warrior, she is a warrior. She lives every day and shes fighting, said the Buffy the Vampire Slayer star.
