Stars Send Well Wishes to Michael Douglas

"He's one of my favorite actors ever," actor Rob Lowe told "Extra's" Lauren Sanchez. "One of my favorite people ever, and he's got everything going for him. Everything."

"Stand Up to Cancer" Co-Founder Katie Couric added, "I think he's remarkably courageous. I think he's so brave to talk candidly and openly about his situation."

Many celebrities had their own personal stories to tell. "I lost a brother to leukemia when he was 4 and I was 10," confessed supermodel Cindy Crawford. "Then two years ago my sister got diagnosed with thyroid cancer. Fortunately, she's doing really well."

"Modern Family's" Sofia Vergara admitted she had thyroid cancer but is now in remission. "I know what it is when you're young and healthy for someone to tell you 'you have cancer'." Her co-star, Eric Stonestreet, said his mom "beat two forms of cancer in the last 8 years."
