- No previous breast cancer.
- No history of breast cancer in a first-degree relative such as a mother or sister.
- No known mutations in the BRCA1 or BRCA2 genes.
- No previous exposure to radiation of the chest wall.
In reply: ""Since one in six women who die from breast cancer are diagnosed in their 40s, we simply cannot afford to see missed opportunities for earlier detection," said Sandra Palmaro, CEO of the Canadian Breast Cancer Foundation."
Martin Yaffe, a professor in the departments of medical biophysics and medical imaging at the University of Toronto, called the recommendations "scientifically unsupportable."
"If followed, they will result in over 2,000 breast cancer related deaths that could be avoided by screening in Canadian women over 10 years," Yaffe said in an email.
Yaffe said the task force ignored scientific data from studies using modern technology that point to a 25 per cent to 30 per cent reduction in mortality through screening.
Women invariably say they're willing to tolerate the stress of having to come in for more imaging tests in exchange for a better chance of not waiting until a cancer is at advanced stage before it is found, added Yaffe, who is also a senior scientist in imaging research at Toronto's Sunnybrook Research Institute.
I hate this stuff. This is worse than insurance companies making medical decisions. This is the government making medical decisions.
