MADRID (AP) -- Spain's royal palace says King Juan Carlos will undergo surgery next month for a lower back disc hernia.
It will be the 75-year-old monarch's second operation in recent months. He had hip surgery last November.
The palace said the king will undergo the hernia operation in a Madrid hospital on Mar. 3.
The king has had several other health issues in the past two years, including knee surgery and the removal of a benign lung tumor.
