Lung Cancer Scans Can be Unreliable

Evidence suggests that CT scans to measure lung tumors can be unreliable. This could potentially lead patients and doctors to believe the cancer is growing when it's not.
A new study found that changes of up to 10 percent can happen simply as a result of the inherent variability of CT imaging.
According to Reuters:
“[The study] ... is the first to test how reliable lung cancer scans are -- work that's long overdue, experts say, because CT scans have already become the gold standard for measuring cancer growth and treatment response.”
