Spanish king JUAN CARLOS I is in hospital undergoing surgery to remove a growth on his lung.
A nodule was discovered on the monarch's right lung last month (Apr10), and now doctors are working to "extract and study" the growth.
A statement from the palace's chief doctor, Avelino Barros Caballero, reveals the 72 year old "is currently undergoing a surgical procedure", reports AFP.
Following the operation, the palace will release further details of the monarch's condition.
