A
 group of experts advising the nation’s premier cancer research 
institution has recommended changing the definition of cancer and 
eliminating the word from some common diagnoses as part of sweeping 
changes in the nation’s approach to cancer detection and treatment. The 
recommendations, from a working group of the National Cancer Institute, 
were published [in] The Journal of the American Medical Association.
 They say, for instance, that some premalignant conditions, like one 
that affects the breast called ductal carcinoma in situ, which many 
doctors agree is not cancer, should be renamed to exclude the word 
carcinoma so that patients are less frightened and less likely to seek 
what may be unneeded and potentially harmful treatments that can include
 the surgical removal of the breast. The group, which includes some of 
the top scientists in cancer research, also suggested that many lesions 
detected during breast, prostate, thyroid, lung and other cancer 
screenings should not be called cancer at all but should instead be 
reclassified as IDLE conditions, which stands for “indolent lesions of 
epithelial origin.” The impetus behind the call for change is a 
growing concern among doctors, scientists and patient advocates that 
hundreds of thousands of men and women are undergoing needless and 
sometimes disfiguring and harmful treatments for premalignant and 
cancerous lesions that are so slow growing they are unlikely to ever 
cause harm. Once doctors and patients are aware a lesion 
exists, they typically feel compelled to biopsy, treat and remove it, 
often at great physical and psychological pain and risk to the patient.
