CHARLOTTE, North Carolina (Reuters) - The grandmother who helped raise Democratic U.S. presidential candidate Barack Obama and whom he had credited with shaping his values has died of cancer, he said in a statement on Monday.

The news came on the day before the presidential election and a little more than a week after Obama interrupted his White House campaign to say goodbye to her in Hawaii.

Madelyn Dunham, 86, died peacefully at her home in Honolulu.

"She was the cornerstone of our family, and a woman of extraordinary accomplishment, strength and humility," Obama and his sister, Maya Soetoro-Ng, said in a statement. "She was the person who encouraged and allowed us to take chances."

Dunham helped raise Obama from the age of 10 while his mother was working in Indonesia, and Obama took an emotional 22-hour trip to visit her on October 23 and 24.

He said afterward his grandmother had been flooded with cards, flowers and well-wishes from around the country, and he regularly thanked crowds at his campaign rallies for their prayers.

"Our family wants to thank all of those who sent flowers, cards, well-wishes and prayers during this difficult time," the statement said.

"It brought our grandmother and us great comfort. Our grandmother was a private woman, and we will respect her wish for a small private ceremony to be held at a later date," the statement said.
