Mammograms linked to breast cancer overdiagnosis

Mammograms may result in healthy women being given unnecessary treatment for breast cancer, according to new research from the Nordic Cochrane Center and Rigshospitalet in Copenhagen, Denmark.

The new study has provided evidence that links routine screening for breast cancer to an over-diagnosis of non-aggressive tumours by comparing outcomes in two separate Danish regions: one that offered biennial mammography for women aged between 50 and 69 and one that did not offer the service.

Speaking to Reuters, Dr Karsten Juhl Jorgensen, of the Nordic Cochrane Center and Rigshospitalet, said: “Overdiagnosis means that healthy women get unnecessary breast cancer diagnoses.”

Dr Jorgensen went on to add: “A breast cancer diagnosis is a life-changing event for the woman and her family, with substantial implications for their quality of life. It also leads to overtreatment with surgery, radiotherapy and sometimes chemotherapy - we know these treatments have serious, sometimes lethal, consequences.”ADNFCR-2094-ID-801830909-ADNFCR
