Misleading Nomenclature Inciting Unnecessary Fear

"The word "cancer" often invokes the specter of an inexorably lethal process; however, cancers are heterogeneous and can follow multiple paths, not all of which progress to metastases and death, and include indolent disease that causes no harm during get the patient's lifetime," says this abstract.  Overdiagnosis and Overtreatment in Cancer: An Opportunity for Improvement

Addressing Overdiagnosis and Overtreatment in Cancer: A Prescription for Change:  "A vast range of disorders—from indolent to fast-growing lesions—are labelled as cancer. Therefore, we believe that several changes should be made to the approach to cancer screening and care, such as use of new terminology for indolent and precancerous disorders. We propose the term indolent lesion of epithelial origin, or IDLE, for those lesions (currently labelled as cancers) and their precursors that are unlikely to cause harm if they are left untreated."  (The Lancet Oncology Volume 15, No. 6, e234–e242, May 2014)
