Robach put on a brave face on ‘GMA’ Monday, saying she is being ‘really aggressive’ about fighting her cancer.
The reporter recounted the fateful "GMA" assignment she received early in October that would eventually save her life.
As part of Breast Cancer Awareness Month, Robach underwent a mammogram live on television, but she admitted to being reluctant to have the medical screening.
"Between flying all over the world for work, and running around with my kids to school and ballet and gymnastics like so many women, I just kept putting it off," she said.

Robach underwent a mammogram live on air in October for ‘GMA.’
It was Roberts - a breast cancer survivor herself - that eventually convinced Robach to take the assignment.
"Thank God you did," she told the news anchor. "I had cancer the whole time we were sitting in that office, and I said, I don't have any connection to that disease."
A routine post-show check-up weeks later quickly led to a "tornado of tests," indicating that Robach's story was only just beginning.

The reporter revealed a post-show check up led to the discovery of her breast cancer.
"I was asked to do something I really didn't want to do, something I had put off for more than a year, I had no way of knowing that I was in a life-or-death situation," Robach wrote, on her ABC News health blog.
"I would have considered it virtually impossible that I would have cancer. I work out, I eat right, I take care of myself and I have very little family history; in fact, all of my grandparents are still alive."

Robach blogged about her shocking discovery, saying she didn't realize the 'GMA' assignment would save her life.
Robach also revealed that upon receiving her diagnosis, her family - including her husband, "Melrose Place" actor Andrew Shue - flew to be by her side and they began "gearing up for a fight."
"On Thursday, Nov. 14, I will go into surgery where my doctors will perform a bilateral mastectomy followed by reconstructive surgery," Robach wrote.
"Only then will I know more about what that fight will fully entail, but I am mentally and physically as prepared as anyone can be in this situation."

The reporter and her husband are parents to five children - Robach has two daughters from a previous marriage, while Shue, 46, has three sons.
"There's a lot you don't know until you have the surgery," she said on air Monday.
