Over-Diagnosis And Over-Treatment Of Cancer In America Reaches Crisis Levels
"We're not finding enough of the really lethal cancers, and we're finding too many of the slow-moving ones that probably don't need to be found," says Laura Esserman, a breast-cancer surgeon at the University of California, San Francisco.
While it's clear that early-stage cancers are more treatable than late-stage ones, some leading cancer experts say that zealous screening and advanced diagnostic tools are finding ever-smaller abnormalities in prostate, breast, thyroid and other tissues.
Many are being labeled cancer or precancer and treated aggressively, even though they may never have caused harm.
“Unfortunately, when patients hear the word cancer, most assume they have a disease that will progress, metastasize and cause death,” the group wrote in the journal Lancet Oncology in May.
As a result, these experts say, many people may be undergoing surgery, radiation, chemotherapy and other treatments unnecessarily, sometimes with lifelong side effects.
