Choosing Wisely:

Don’t routinely drain non-painful fluid-filled breast cysts.

Rationale and Comments: Breast cysts are common. They are harmless fluid filled sacs. If an ultrasound (sonogram) confirms that a breast mass is a simple cyst, it does not need to be drained unless it is bothersome to the patient or if there are concerns it could be something other than a cyst or has complex characteristics.
