Emmy Award-winning Desperate Housewives
actress Kathryn Joosten, 69, underwent surgery Monday morning in Los Angeles to remove a cancerous growth on her lung, PEOPLE has learned.
According to Joosten's rep, the actress's doctors believe the cancer was well contained – and that the surgery was a complete success.
"She's doing great," her rep says. "She'll be in the hospital recovering for a few days. And she'll need to go in for proactive CAT Scans every few months. But there will be no [need for] chemo, no radiation."
Joosten, who plays feisty neighbor Mrs. McCluskey on the ABC show, had already survived a bout with lung cancer in 2001. She learned she had cancer again
just last month – after doctors discovered a spot on her left lung during a routine chest X-ray Sept. 9. "I've got a little hang-up here," Joosten told PEOPLE at the time, "but we're going to handle it and move forward."
According to her rep, that's exactly what she's done.
"She'll be back to her feisty old self, chasing her old man down the street any day now," he adds.
