In an interview airing Tuesday morning on ABC's "Good Morning America," Christina Applegate declares that she has won her brief battle with breast cancer, but that she had to make the dramatic decision to have both of her breasts removed to increase the chances that it would not return.

"My decision after looking at all the treatment plans that were possibilities for me, the only one that seemed the most logical, and the one that was going to work for me, was to have a bilateral mastectomy," she tells Robin Roberts.

She says she decided to make that decision to increase her chances that the cancer would not return. "I didn't want to go back to the doctors every four months," she says. "I wanted to be rid of it. For me this was the choice I made and it was a tough one."

Although she knows she made the right decision, she still finds her self breaking down at times.

"Sometimes I cry and sometimes I scream and I get really angry," she says. "It's all a part of healing and anyone who's going through out there, it's okay to cry. It's okay to fall on the ground and just scream if you want to."

But things are looking up for the actress, who says in the interview that she's now cancer free. "Absolutely 100 percent clear and clean," she says. "They got everything out, so I'm definitely not going to die from breast cancer."

The full interview will air on "Good Morning America" on Tuesday at 7 a.m.
