"I know enough to save my own life, and that was very important to me," said Albright, who is one of the women included in the reports.
In the report that aired Thursday, the 28-year-old Albright is shown with her shirt open and arms raised. She uses the pads of her fingers to feel each breast carefully, going in a circular motion.
Pennybacker said t it wasn't difficult for the station to find participants for the reports.
"To find somebody was not a problem at all," she said, "because they understood to instruct someone on a breast self-exam, they need to see the breast."
The fact that the series started to air on the first day of the "sweeps" period -- when ratings are all-important -- is not lost on critics like Wright. But Bill Lord, the station's general manager, said there was a bigger purpose.
"The doctors we have talked to and the experts we have talked to say to really learn this correctly, you need to actually see them," Lord told "Good Morning America." "This is not something we have devised for our own purposes. It really is responding to professionals."
In an interview with The Washington Post Thursday, Lord said he wasn't bothered by the timing of the reports.
"Yes, this is an attention-getting story, but it's also an important story," he told the Post.
Pennybacker said that viewer reaction to the reports has been positive.
"We have had overwhelming support," she said. "From men, from women, people are very happy about how this was handled."
Roberts, whose own breast cancer was diagnosed through a self-exam, asked what inspired the two reporters to participate in the series.
"[Breast cancer] touches every single person," Parker said. "We hope that that's not the case moving forward."
