While therapy has improved quite a bit since 1985, the greatest benefit derives from most women avoiding the need for life-long treatment by having small tumors found and removed before they’ve spread.
Some of the more understandable discussion comes from women with metastatic disease whose tumors were missed by screening mammography. Notably, neither paper quotes an oncologist.
Days ago, the USPSTF issued a new draft for its recommendations on routine PSA measurements in asymptomatic men. The panel’s report is published in the Annals of Internal Medicine. The main findings are two: first, the absence of evidence that routine PSA testing prolongs men’s lives, and second, that PSA evaluation may, on balance, cause […]
The risks and costs of breast cancer screening are exaggerated and misrepresented in the recent news…. My conclusion is that rather than ditching a life-saving procedure that’s imperfect, we should make sure that all doctors and radiology facilities are up to snuff.
We need to distinguish between errors in the measurement (cancer or not) and errors in decisions that we – patients and doctors – make after upon detecting a premalignant or early-stage malignancy in a woman’s breast.
Why bother, you might ask – wouldn’t it be easier to drop the subject?
“Make it go away,” sang Sheryl Crow on her radiation sessions.
I’ll answer as might a physician and board-certified oncologist who happens to be a BC survivor in her 40s: we need establish how often false positives lead, in current practice, to additional procedures and inappropriate treatment…These numbers matter. They’re essential to the claim that the risks of breast cancer screening outweigh the benefits.
Three key issues have escaped the headlines: 1. The expert panel carried out a careful analysis using data that are, necessarily, old; 2. The recommendations don’t apply to digital mammography; 3. Mammograms are not all the same.
We need to set the bar higher for mammography…
But consider – if the expert panel’s numbers are off just a bit, by as little as one or two more lives saved per 1904 women screened, the insurers could make a profit!
By my calculation, if one additional woman at a cost of, say, $1 million, is saved among the screening group, the provider might break even. And if three women in the group are saved by the procedure, the decision gets easier…
Now, imagine the technology has advanced, ever so slightly, that another four or five women are saved among the screening lot.
How could anyone, even with a profit motive, elect not to screen those 2000 women?
Smack in the midst of October-is-breast-cancer-awareness-month, the Journal of the American Medical Association published a provocative article with a low-key title: “Rethinking Screening for Breast Cancer and Prostate Cancer.” The authors examined trends in screening, diagnosis and deaths from cancer over two decades, applied theoretical models to the data and found a seemingly disappointing result.
It turns out that standard cancer screening is imperfect.
The subject matters, especially to me. I’m a medical oncologist and a breast cancer survivor, spared seven years ago from a small, infiltrating ductal carcinoma by one radiologist, an expert physician who noted an abnormality on my first screening mammogram…
