AP: Kennedy Responding Well To Treatment

Sen. Edward Kennedy is responding well to radiation and chemotherapy treatments for brain cancer, his wife reported in an email to friends and family obtained Monday by the Associated Press.

Kennedy is fatigued, but otherwise doing well, the AP reports.

In the e-mail, which was sent out last  Wednesday but obtained by the AP Monday morning, Vicki Kennedy said her husband has been exercising each morning before heading to Boston for treatment at Massachusetts General Hospital. By afternoon, he's back in Hyannis Port.

According to the email, Vicki Kennedy says her husband describes his cancer as "a bear," but she thinks of his reputation as a political fighter and is "betting on the lion," a reference to Kennedy's nickname.

Kennedy underwent surgery at Duke University Medical Center in North Carolina on June 2 and has been treated since in Boston.
