Study Suggests Women May Be Better Off Without Mammograms

Ditch the yearly mammograms?
A new study suggests that some breast cancers detected by mammography could have vanished on their own had they not been detected and treated, according to a study published today in the Archives of Internal Medicine.
Researchers from Dartmouth Medical School and Norway studied the estimated value of screenings and, for six years, compared the number of tumors in female breast cancer patients aged 50 to 64 who received a single mammogram with a group of women of the same age who had been screened on up to three occassions. Considering that the risk factors are similar for both groups, one would expect the tumor rates to be the same. They weren’t. The rate in the single-screen group was about 22% lower. The conclusion: Not all tumors found in a mammogram necessarily need treatment. They may not even be cancer.
"Some breast cancers will not continue to behave as cancers, even though they look like cancer under the microscope, and they grow and reach a size where they can be detected on mammograms," Jan Maehlen, M.D., Ph.D., a study co-author, told WebMD. "But if they had been left intact [instead of treated after detection], some will stop growing and shrink and disappear over a course of perhaps two years."
And the implication of these findings could change the way women think about breast-cancer treatment. That’s what Robert M. Kaplan, Ph.D., suggests in an editorial accompanying the study: "Despite the appeal of early detection of breast cancer, uncertainty about the value of mammography continues," Dr. Kaplan, chairman of the department of health services at the School of Public Health at the University of California, Los Angeles, wrote in the editorial.
So, are mammograms pointless? Absolutely not!
According to the American Cancer Society, the study’s conclusion is an "overreaching leap in logic." Robert A. Smith, who heads that group, went on to describe the findings as a "simplification" and "alarming."
The benefits of mammograms far outweigh the potential risks and definitely save lives every day.
What this study does suggest is that, if undetected, some cancers might regress, but that notion’s been proven in the past. The New York Times points out that there have been instances where patients’ melanomas or kidney cancers have just vanished. Neuroblastoma, cancer that forms in a child’s nerve tissue, has reportedly disappeared without treatment.
