Brief summary: The objective of this study is to demonstrate the efficacy and response of novel Magnetic Resonance Imaging (MRI)-guided ultrasound stimulated microbubble treatment to enhance radiation effects in humans receiving external beam radiotherapy delivered using a LINAC (linear accelerator) radiation therapy device.

Detailed description: The approach uses relatively low-power ultrasound, operating with lower power levels than high intensity focused ultrasound and ultrasound-based hyperthermia techniques, delivered on the Sonalleve platform. The tumour will be sonicated before the radiation to enhance the effect of therapy. The technique is spatially targeted and stimulates microbubbles using low-power ultrasonic fields in the tumour location only. The primary aim is to evaluate tumour response to MRg-FUS + MB and radiation, as measured radiologically or clinically within the treated therapeutic target regions.The secondary aim of this research is to evaluate early and late effect profiles of MRI- guided ultrasound stimulated microbubble treatment and radiation in patients with inoperable breast/chest wall tumours or LABC at 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after treatment.

Eligibility criteria: Inclusion Criteria:

* Age ≥ 18 years.
* All biopsy-confirmed invasive ductal, invasive lobular and other rare histologic types of carcinoma.
* Patients with early stage Breast cancer, or LABC ; i.e., Stage IIA - IIIC cancers (T2 N0 M0 to Any T, N3, M0) or Stage IV (Any T, Any N, M1) per AJCC guidelines (8th Edition).
* Assessed as indicated, by a multidisciplinary team of treating medical, surgical and radiation oncologist and found suitable for radiation treatment.
* Patient referred for standard palliative radiotherapy or curative radiotherapy, which may include (but are not limited to) any of the following dose regimens: 1) 5-8 Gy in one fraction, 2) 20 Gy in 5 fractions, 3) 30 Gy in 5 fractions, 4) 35 Gy in 5 fractions, 5) 30 Gy in 10 fractions, 6) 40 Gy in 10 fractions, 5) 50 Gy in 20 fractions, 6) 60 Gy in 30 fractions and 7) 66 Gy in 33 fractions, or radiobiologically similar doses.
* Able to understand and give informed consent.
* Weight \< 140 kg.

* Creatinine within normal institutional limits or creatinine clearance \>60 mL/min/1.73 m2 for patients with creatinine levels above institutional upper limit of normal.

Exclusion Criteria:

* Pregnant or lactating women may not participate due to the embryotoxic effects of protocol treatment.
* Unable to have a contrast-enhanced MRI scan - standard of care criteria.
* Patients having received anthracycline or taxane based chemotherapy within the past 5 days.
