Recalling a moment of feeling "invincible" back in her Beverly Hills, 90210 days, Shannen dished of the episode her character, Brenda, had to have a biopsy after a lump was found in her breast. She shared:
"I remember that episode because it really meant a lot to me. Back then I was a kid, man, I thought that I was invincible, I thought I was going to live forever."
That just breaks our heart.
Even speaking of one of her low points since fighting cancer, the 45-year-old confessed to breaking down to her husband Kurt Iswarienko about their time left together:
