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.
