Would this be solved by routine scans, so you have a baseline you can compare against? Ignore anything slightly odd in the first scan but monitor for changes over time?

Wouldn't help much.

* Some kind of scans, like CT scans, use ionizing radiation and should not be done too often. * Looking at only imaging scans it is often impossible to tell apart a cancer and a benign growth. (More invasive tests would still be required, which was what the parent posters were warning about)
