Local women who have unwanted bras are being asked to donate them to the UHMBT.
For every tonne of bras collected, the Morecambe Bay Hospitals Trust will donate £1,000 to breast cancer research.
The donated bras will then be sent to developing countries in Africa.
Collection points are on Ward 7 at Westmorland General Hospital in Kendal, the Emergency Department at Furness General in Barrow, and at the Oncology Outpatients department at the Royal Lancaster Infirmary.
More information on the campaign is on the Against Breast Cancer website here.
