SERUM BIOMARKERS: Blood work will be obtained on the day of baseline imaging, immediately after each cycle of anthracycline, and on the day of post treatment imaging . At each time point samples of bio-banking will be collected. Blood sample collection will be done locally at the participant's respective site and transferred to University Health Network (UHN) biobank for future analysis or analysis of markers that are not available at all sites (e.g. high sensitivity troponin I and BNP).
