just be wary of those that promise 'same day' results on screenings. oftentimes the radiologist is overwhelmed and may miss a cancer. for example, in our office, the radiologist reads the screenings before and after clinic, when things are quiet. During clinics, we are seeing diagnostics and recalls and they concentrate on those. I use to work for an independent radiologist who missed ALOT of cancers trying to run too many people thru. If you go to a place that reads right away, make sure they have more than one doc there, otherwise you may be taking a big chance.
Think about this too: how many tests do you get the results right away? blood work, no. regular xray, no. ekg, no.
Quick results do not mean right results.
