Two more screens per woman would improve effectiveness of UK breast cancer screening

The NHS breast screening programme provides mammography for women aged 50-64 years every three years. However, this may not be the optimum screening policy. Boer et al (p 376) used a simulation model to estimate the effects and costs of shortening the screening interval to two years and raising the age of final invitation to 69. Both alternatives require two more invitations per woman and are predicted to lead to a substantial increase in the number of deaths prevented and life years saved. Extending the age range would prevent more deaths but shortening the interval would save more life years. The current screening policy costs £2522 per life year gained; the cost of each additional life year gained would be £2990 for extending the age range and £3545 for shortening the screening interval.
