A council health watchdog will look at the impact of the suspension of breast screening in Cumbria.
In August, it emerged nine women had cancer having originally been given the all clear after screening.
It came after North Cumbria University Hospitals NHS Trust announced in July that screening was being temporarily halted for a major review.
Cumbria County Council's health and wellbeing scrutiny committee will discuss the service on Tuesday.
The review involved 1,600 women who had had further tests following routine mammograms since April 2007.
Trust officials decided to hold the review when data showed that among women who were called for a second screening, cancer was detected in fewer cases than would be expected.
The committee will look at the impact of the suspension on the speed of appointment, assessment and treatment of patients.
They are looking for assurances that future arrangements will ensure that Cumbrian women receive a similar service to elsewhere.
The committee will also look at whether people still have access to Patient Transport Services when they need it following a change in eligibility guidelines.
