Actress Kim Novak is undergoing treatment for breast cancer.

Novak's manager says the 77-year-old "Vertigo" actress will receive "minimal" treatment, as the cancer was caught early by a routine mammogram and that she is in "fantastic physical shape."

Manager Sue Cameron says Novak works out with a trainer three times a week and rides horses daily.

Cameron says Novak is expected to "be just fine."

"The Man With the Golden Arm" star appeared in a string of films in the late 1950s and 1960s.

She lives in Oregon with her husband.
