The magnetic resonance imaging results of Sisi's post-operative check-up one week later showed that the liver metastases had slightly shrunk. The edema was more noticeable than before, evenly distributed, its edges perfectly tracing the original outline of the tumor.
This type of MRI manifestation shows that at the time, the focused ultrasonic waves provided a full-dimensional bombardment of the tumor, without any omission or exceeding the tumor's range, achieving the goal of precision targeting.
However, even so, there would still be residual tumor cells. These cells slowly divide and eventually return, a fate shared by all advanced malignant tumors. Once distant metastasis occurs, it is almost impossible to eradicate them completely.
That is why the principle of "early detection, early diagnosis, and early treatment" is advocated for tumors. When the cancer cells have not yet spread and are confined to a local space, they can be completely removed with a single surgery.
