Experimental: MRg-FUS MB Treatment
Patients with locally advanced breast cancer (LABC) and chest wall tumours will receive MRI-guided ultrasound-stimulated microbubble-treatment combined with radiotherapy on a LINAC.

- Incidence of toxicity and adverse events using MRg-FUS+MB treatment in patients with chest-wall and locally advanced breast cancer [ Time Frame: 90 days ]Incidence of toxicity and adverse events
- Radiological Response [ Time Frame: 90 days ]The secondary endpoint is radiological response in breast cancer following MRg-FU + MB + radiation, after a 3 month follow up.
