Many Early Detected "Cancers" Are Not Fatal, Not Cancerous And Not Malignant: Top Cancer Scientists Call For Restricting "Cancer" Use As A Diagnostic Term

From The New York Times, "Scientists Seek to Rein In Diagnoses of Cancer" by Tara Parker-Pope:

A group of experts advising the nation’s premier cancer research institution has recommended sweeping changes in the approach to cancer detection and treatment, including changes in the very definition of cancer and eliminating the word entirely from some common diagnoses.

The recommendations, from a working group of the National Cancer Institute, were published on Monday 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.”***"We need a 21st-century definition of cancer instead of a 19th-century definition of cancer, which is what we’ve been using," said Dr. Otis W. Brawley, the chief medical officer for the American Cancer Society, who was not directly involved in the report.

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.

The advent of highly sensitive screening technology in recent years has increased the likelihood of finding these so-called incidentalomas — the name given to incidental findings detected during medical scans that most likely would never cause a problem. However, 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. The issue is often referred to as overdiagnosis, and the resulting unnecessary procedures to which patients are subjected is called overtreatment.

Officials at the National Cancer Institute say overdiagnosis is a major public health concern and a priority of the agency. "We’re still having trouble convincing people that the things that get found as a consequence of mammography and P.S.A. testing and other screening devices are not always malignancies in the classical sense that will kill you,” said Dr. Harold Varmus, the Nobel Prize-winning director of the National Cancer Institute. “Just as the general public is catching up to this idea, there are scientists who are catching up, too."
