March 6 (UPI) -- Shannen Doherty was feeling "great" as she returned to the red carpet Saturday.
The 45-year-old actress attended the Animal Hope and Wellness Foundation Gratitude Gala in Los Angeles after completing chemotherapy and radiation for cancer. Doherty was accompanied by the organization's founder, Marc Ching.
"I feel great," the star told People at the event. "I feel great, I feel, like, lucky. Lucky that I'm here, lucky that I'm standing next to Marc, lucky that I get to be a part of this foundation, lucky that we get to be a voice tonight for the voiceless and just lucky."
"I'm happy with where I'm at right now," she added to Us Weekly. "Cancer, for me, as hard as it is, has been a blessing. It has changed who I am as a human being forever. It's altered my life in ways I can't even speak of."
Doherty was diagnosed with breast cancer in 2015, and announced in August that the disease has spread to her lymphatic system. She told fans last week on Instagram that she had finished her cancer treatments.
"Last day of chemo. Exhausted. Now that I'm done with chemo and radiation, the waiting game is here," the actress wrote at the time. "Waiting for test. Waiting to see if I'm clear or not. Waiting for reconstruction. Waiting."
"I think when one gets cancer, they are always waiting to a certain extent. To those who know... I'm waiting with you. #cancerslayer," she added.
Doherty is known for playing Brenda Walsh on Beverly Hills, 90210, and Prue Halliwell on Charmed. She will appear in the series MallBrats and a TV Land reboot of Heathers.
