Marcia Cross may be spending a bit more time at a hospital than on Wisteria Lane for awhile.

The Desperate Housewives star's husband Tom Mahoney, 50, has been diagnosed with cancer, E! News confirms.

"He is currently under treatment and is responding very well," the actress' rep, Heidi Slan, says, declining to elaborate further.

The Emmy nominee, 46, and her stockbroker beau married in 2006 and have twin daughters, Eden and Savannah, who are nearly 2.
