NEW YORK—Christina Applegate is taking the long view of her battle with breast cancer—the really long view.

Speaking on ABC News’ “Good Morning America” in her first interview since announcing her diagnosis earlier this month, the “Samantha Who?” star said she had a double mastectomy three weeks ago. She’ll undergo reconstructive surgery over the next eight months.

“I’m going to have cute boobs ‘til I’m 90, so there’s that,” she joked in the interview, which aired Tuesday. “I’ll have the best boobs in the nursing home. I’ll be the envy of all the ladies around the bridge table.”

The 36-year-old actress elected to remove both breasts even though the disease was contained in one breast. She said she is now cancer-free.

Applegate called the operation a logical decision. Her mother battled breast cancer, and she tested positive for the BRCA1 gene mutation linked to breast and ovarian cancer.

“I just wanted to kind of be rid of it,” she said. “So this was the choice I made and it was a tough one.”

Applegate’s cancer was detected early through a doctor-ordered MRI. She said she’s starting a program to help women at high risk for breast cancer to meet the costs of an MRI, which is not always covered by insurance.
