Is umbilical hernia rare in a 66 year old women?

Umbilical hernias are not uncommon in adults, including 66-year-old women. They occur when a portion of the abdominal contents, such as the intestines, protrude through a weakness in the muscles of the abdominal wall near the navel. While they are more common in infants and children, they can also develop in adults due to factors such as aging, obesity, pregnancy, and chronic coughing.
