I had some pain in my lungs and they gave me an xray in about 30 minutes here in Spain to confirm that i had pneumonia. I waited 45 min to see the doctor in the emergency room and then another 10min waiting for the doc to check the xrays.
But for the majority, it isn't great. You go with pain in stomach and it happens to be cancer, you die waiting. I personally have seen so many of these and it's heartbreaking.
