Teresa Heinz Kerry said she is being treated for breast cancer at Massachusetts General Hospital and will undergo radiation next month.
Heinz Kerry, 71, said doctors discovered she had cancer in her left breast in September during her annual mammogram. She is the wife of US Senator John Kerry of Massachusetts.
In early October, she underwent lumpectomies on both breasts at a Washington hospital after doctors also discovered what they thought was a benign growth on her right breast.
