High-intensity ultrasound may launch attack on cancer, wherever it lurks
...ells, including those that have spread through the bloodstream to lurk in other parts of the body. This high-intensity focused ultrasound, or HIFU, is in use or testing in China, Europe and the United States to kill tumors by heating them. But Duke researchers now find that HIFU might work even better if it is...Marijuana component opens the door for virus that causes Kaposi's sarcoma
