WASHINGTON — She made us laugh as Elaine on “Seinfeld” and Selina on “Veep.”

But on Thursday, Julia Louis-Dreyfus announced her most challenging role: cancer patient.

The TV actress posted on Instagram that she has been diagnosed with breast cancer.

The actress just won her sixth straight Emmy at Selina Meyer on the HBO comedy “Veep,” breaking the record by Candice Bergen (“Murphy Brown”) for the most by one character.

When you add “Seinfeld” and “The New Adventures of Old Christine,” she has racked up eight acting Emmys, tying Cloris Leachman for the most ever by a single performer. If you add her behind-the-scenes role as a “Veep” producer, her total Emmy count climbs to 10.
