US. There are walk in clinics all over that take people first come first serve (once in a while the receptionist says no way and sends you to an ER where they take people in priority order). Generally they are open 9am-8pm 7 days a week, though it varies by location. These are called urgent care and for are things that you need urgent but non-emergency care for - you typically get an antibiotic or some such treatment (depending on what you have) and are sent home. Depending on what you have sometimes you are told to make an appointment with your regular doctor, sometimes sent to a hospital.

My regular doctor I do need to make an appointment to see. Typically I can get an appointment in about a week anytime I call, though normally I just make the next appointment as I leave the last one and so they are months out.

Wait… you’re saying she went to urgent care and that urgent care did a cancer screening?

Urgent care is great, but they usually don’t have MDs. There are nurses that can give you stitches or a course of antibiotics but a cancer diagnosis is way out of their expertise

Every provider / system is different. My wife is a physician who works urgent care shifts over the weekend to serve patients as described above. These are in addition to her M-Friday routine. She is part of the Kaiser system. This is systemwide for Kaiser, so my wife’s weekend engagement isn’t a one-off.

I don't know what happened after arriving. They likely did sometests and then found a hospital to admit her. Then the hospital did more tests.

The important point here is her fitness tool alerted her to something and that startee the chain that eventually found the real problem.
