> That's because some cancers grow slowly and never become dangerous...These false-positive tests led to more follow-up testing, including risky procedures like a biopsy, which inserts a needle into the lung. > "Not surprisingly," Welch says, "sometimes that creates problems like causing someone's lung to collapse." These outcomes should inform whether or not the biopsy needs to take place or whether they should instead follow up with further screens to monitor whether the cancer progresses. Of course, the major downside of my suggestion is that patients are extremely reluctant to hear "cancer" without a plan to rapidly classify it as malignant or benign.
