The four-day summit, which takes place from 15-18 April 2012, is expected to contribute more than £500,000 to the local economy.
Visit Manchester worked with Dr Robert Clarke, a senior lecturer at The University of Manchester’s School of Cancer and Enabling Sciences and a member of the Manchester Cancer Research Centre, in the bid to bring the meeting to the city.
Visit Manchester managing director Paul Simpson said: "This is another example of the Conference Ambassador Programme in action. There are a number of organisations and facilities in Manchester that work in the field of cancer treatment and so the city is a natural host for a meeting of this type."
Dr Clarke added: "Manchester Cancer Research Centre want to improve cancer treatment for patients, and hosting a conference for the world’s best breast cancer researchers here in Manchester is one part of the strategy to achieve that goal. We have organised an exceptional programme and hope that many scientists and clinicians from around the globe will attend and help us improve prevention and cure for breast cancer."
