The New York Times‘ Gina Kolata reports that the American Cancer Society, a longtime defender of early detection and cancer screening, is planning to release an online message next year “to emphasize that screening for breast and prostate cancer and certain other cancers can come with a real risk of overtreating many small cancers while missing cancers that are deadly.”

“We don’t want people to panic,” said Dr. Otis Brawley, chief medical officer of the cancer society. “But I’m admitting that American medicine has overpromised when it comes to screening. The advantages to screening have been exaggerated.”
The ACS’ change of heart on breast and prostate screening was inspired, in part, by a recent analysis published in JAMA.
In it, researchers report a 40 percent increase in breast cancer diagnoses and a near doubling of early stage cancers, but just a 10 percent decline in cancers that have spread beyond the breast to the lymph nodes or elsewhere in the body. With prostate cancer, the situation is similar, the researchers report.
In an interesting side note, Kolata includes a quote from Colin Begg, a biostatistician at Memorial Sloan-Kettering Cancer Center in New York, that shows a different perspective on media coverage of the screening debate.
“I am concerned that the complex view of a changing landscape will be distilled by the public into yet another ‘screening does not work’ headline,” Begg said. “The fact that population screening is no panacea does not mean that it is useless,” he added.
Kolata’s story was published on Tuesday. On Wednesday, the ACS released a statement from Brawley in which he says the organization stands by its screening recommendations. In the statement, Brawley says ACS “stands by its recommendation that women age 40 and over should receive annual mammography” and that its recommendation that men consult with their doctors to “make an informed decision about whether or not prostate cancer early detection testing is right for them. ”
