A medical negligence case is being prepared by a group of women who were wrongly given the all-clear from breast cancer.
The six patients are seeking compensation from East Lancashire NHS Trust, after screenings conducted by consultant Dr Glenn Kelly failed to spot tumours.
Hospital bosses have pledged to work with the women over the claims, after it emerged that a total of 335 mammograms had to be re-checked.
A second breast examination was required for 85 women, with 14 being told they had invasive breast cancer.
Chairman of a trust health watchdog Roy Davies commented: "If these ladies have been mistreated the trust is responsible and they have just to accept it," adding that the hospital would have to "pay up and take it on the chin" if the women are found to be entitled to compensation.
East Lancashire Hospitals NHS Trust employs around 7,000 staff across its four sites.
Paul Sankey, a medical negligence partner at Russell Jones & Walker, commented: "Being diagnosed with cancer is devastating enough without discovering that medical errors have made the condition worse. Compensation cannot change the past but it can make it easier to deal with some of the financial implications of fighting with cancer."
