Lori Allen -- star of TLC's reality show Say Yes to the Dress: Atlanta -- recently revealed that she's battling breast cancer and we've got a preview of a special episode in which she breaks the news to her stunned staff.  

"How do you tell people that you have cancer?" Allen explains in this clip, right before she reveals her diagnosis to her employees at her story Bridals by Lori. "You don't want people to feel sorry for you, that is the last thing I want."

"I went in for a regular mammogram, and the results came back positive, and I have breast cancer," Allen announces. "I've got to have surgery and I'm going to be out for quite a while." Staff members are visibly upset after hearing Allen's revelation, but they resolve to keep the store operating successfully while their boss recovers. 

In a special one-hour special entitled Say yes to the Cure: Lori's Fight, Allen opens up about her "devastating" cancer diagnosis in April and her struggle to beat the disease. "Wanting to turn something very negative into something positive, I decided to share my journey -- in hopes that I can raise breast cancer awareness and perhaps help other women facing breast cancer be less afraid," she explained.
