The aim of this study is to evaluate the efficacy of real-time guidance\u002Fmonitoring and ablation\u002Fsonoporation method. The hypothesis behind this proposed study is that High Intensity Focused Ultrasound (HIFU) can be used to ablate tumor tissue, and microbubble-mediated Low Intensity Focused Ultrasound (LIFU) can be used to sonoporate tumor vasculature. The investigators of this study also hypothesize that HMI can be used to monitor HIFU ablation by measuring the changes in tissue stiffness that occur as a result of thermal ablation, guide LIFU sonoporation and HIFU ablation targeting stiff tumor tissue, and the HMI-monitored stiffness changes during ablation will correlate with post-treatment immune response. The ultimate goals of this study are: first, to assess whether these techniques can be used in the clinic in order to provide a well-monitored, noninvasive tumor ablation\u002Fsonoporation method for benign tumors and breast cancers, to minimize side effects due to invasiveness and enhance therapeutic effects of current methods; second, to make full use of the real-time monitoring capability of HMIgFUS for more precise, point-of-care treatment planning to ensure success of ablation\u002Fsonoporation and immune activation.",[91,92],"Fibroadenoma","Breast Cancer Stage I","2026-08-11",{"date":95,"type":96},"2026-08-13","ACTUAL",{"date":98,"type":96},"2022-01-19",{"date":100,"type":85},"2031-05",{"name":5,"class":6},1]
