WebAbstract. Ultrasound can be focused into deep tissues with millimeter precision to perform non-invasive ablative therapy for diseases such as cancer. In most cases, this ablation uses high intensity ultrasound to deposit non-selective thermal or mechanical energy at the ultrasound focus, damaging both healthy bystander tissue and cancer cells. WebOther factors might also play a role in how likely it is that a person exposed to radiation will develop cancer. For example, some genetic conditions can make a person’s cells more vulnerable to radiation damage, which might in turn raise their risk more than in someone without these gene changes.
