New soundwave treatment shows promise in killing cancer cells

A new cancer treatment called histotripsy uses focused soundwaves to destroy tumors. Chris Donaldson, diagnosed with ocular melanoma that spread to his liver, is cancer-free two months after receiving this FDA-approved therapy at Providence Mission Hospital. Histotripsy offers advantages over traditional treatments like radiation. It uses ultrasound waves to rupture cancer cells without affecting surrounding tissue. The procedure is non-invasive, requiring no incisions, and can be repeated as needed. Early studies suggest histotripsy may also enhance the body's defenses against cancer. Doctors plan to explore its use for other organs, such as the thyroid and breast tissue. Donaldson credits the treatment with saving his life and allowing him to spend time with his family.
