The hospital network is teaming up with the medical device company Siemens Healthineers for the event.
The event is for uninsured women over 40 who can receive a mammogram at no cost. Registration is required and as of Monday morning, all appointments have been filled.
However, there is a very limited capacity for walk-ins each day but you will need to call first to check availability at this number: 919-350-1317
The bus will be parked at WakeMed's Raleigh Medical Park.
The mobile suite will be open daily from 8 a.m. until 4 p.m.
Next week the hours will be 11 a.m. to 7 p.m.
The event runs until October 31.
