Estela Casas is celebrating another milestone in her yearlong battle with breast cancer.

The longtime television news anchor recently received her last treatment of immunotherapy and took to social media to express her joy and gratitude in an emotional video post. “It’s an important day today, Sept. 6,” she begins the minute-long clip.

“A year ago today, I was…grappling with the fact that I had just been diagnosed with bilateral breast cancer. A year later – today – I’m having my last treatment of Herceptin immunotherapy.”

Herceptin is a targeted therapy medicine used to treat both early and late-stage breast cancer, according to the American Cancer Society. It is given after surgery to reduce the risk of recurrence.

Appearing to fight back tears, Estela then speaks about the treatments and surgeries she’s endured in what she’s referred to as her cancer journey. “I have undergone 6 chemotherapy [treatments], double mastectomy, reconstructive surgery, and today finishes the 18th infusion of Herceptin.”

“I’m celebrating because when you celebrate you validate what you’ve been through,” she explains.

“So, thank you to everyone who has said a prayer for me, has sent me a card, has sent me an email, has wished me the best,” she concludes. “We got through this together and I’m so very grateful to God and so very thankful to you. “

Estela has been very open throughout her ordeal, so this is not the first time she has publicly celebrated a milestone since revealing the devastating diagnosis last September. In December 2017, she took to Facebook to celebrate her last day of chemo, and this past July she ditched her wig on live TV opting to embrace her “new and curly” ‘do.
