How does adenoid cystic carcinoma spread?

Adenoid cystic carcinoma usually spreads along nerves or through the bloodstream. It spreads to lymph nodes in approximately 5% to 10% of cases. When ACC metastasizes (spreads) beyond the lymph nodes, it most commonly spreads to your lungs. In most cases, lung metastases grow very slowly over months and even years.

Local recurrence (return of cancer) is more common than distant metastasis. This happens when cancer spreads along the nerves of your face. It can be aggressive and difficult to treat.
