Teresa Heinz Kerry, the wife of U.S. Secretary of State John Kerry, was rushed to a Massachusetts hospital on Sunday, after taking critically ill with an unspecified medical condition while on the island of Nantucket, south of Cape Cod, Mass., news reports said.

Heinz Kerry, 74, was accompanied by her husband when she was taken to Nantucket Cottage Hospital, a critical access affiliate of Massachusetts General Hospital, CNN reported, citing Glen Johnson, the secretary’s spokesman.

She was transferred to Massachusetts General Hospital in Boston, after her condition became stable.

“The family is grateful for the outpouring of support it has received and aware of the interest in her condition, but they ask for privacy at this time,” Johnson said in a statement.

Heinz Kerry is the widow of John Heinz, a former Pennsylvania senator and heir to the Heinz ketchup and condiment business. She married Kerry in 1995, four years after Heinz died in a plane crash.

Heinz Kerry who was diagnosed with breast cancer in 2009 and was treated with surgery and radiation, spoke to CNN’s Larry King, in 2010, about her cancer, saying: “I wasn't scared because I'm very analytical about things like this. I’m kind of, I guess, a little fatalistic,” CNN reported.

Heinz Kerry, who is a philanthropist and an environmentalist, was born in Mozambique, and has worked for the U.N. as an interpreter after learning five languages, according to USA Today.
