Today’s Debate Over Mammography?
I had never heard about Dr. Alice Stewart, I read about her the other day …in the 1950s, she asked an uncomfortable question.
When childhood leukaemia was rising, Dr. Stewart and her colleagues investigated the histories of children who had died from cancer. She discovered an association: children whose mothers had undergone diagnostic X-rays during pregnancy were more likely to develop childhood cancer.
She published the findings in The Lancet in 1956. But, her conclusions were challenged.
She lost her funding became difficult.
Her Oxford research unit received no further Medical Research grants, and she was unable to continue the work at Oxford.
That did not mean she stopped asking questions.
Eventually, medicine’s understanding of radiation saw routine prenatal X-rays disappeared.
This got me thinking about something that I see discussed often: mammography.
Recently the Swiss Medical Board concluded that on balance of benefits and harms when it comes to mamograms was unfavorable enough that it recommended against introducing new systematic screening programs and proposed eventually phasing out existing ones.
We should be willing to ask the same kind of questions Alice Stewart asked:
What does the evidence actually show?
What is the absolute benefit for a woman of this age and risk profile?
What are the risks?
How common are false positives?
How much overdiagnosis occurs?
What are the consequences of screening more frequently?
Are there circumstances where another imaging method is appropriate?
And most importantly:
Is the woman being given enough information to make that decision for herself?
That’s the connection between Alice Stewart’s story and the mammography debate.
The lesson of Stewart isn’t that radiation is always too dangerous to use.
It’s that medical practices involving radiation should never be placed beyond scrutiny simply because they are established practice.
The question shouldn’t be: Are you for or against mammography?
The better question is:
Do women have the evidence they need to make a genuinely informed choice?
