Utilize Ultrasound to Combat Cancer Tumors

Innovations in Cancer Treatment

Cancerous tumors, resulting from the uncontrolled growth of cells, pose a significant problem for multicellular organisms, including humans. Therefore, eliminating these rogue cells becomes essential for ensuring long-term existence. However, destroying them without affecting healthy cells presents a challenge. Traditional treatments, such as chemotherapy, are often harsh on the body, while radiation therapy takes a more targeted approach.

An intriguing option is the utilization of ultrasound, and the IEEE Spectrum recently covered a company providing equipment for histotripsy. Ultrasound has diverse applications in the medical field, extending beyond imaging to encompass a variety of therapeutic methods that act within the body without the need for incisions. By using high-energy ultrasound, it is possible to accurately target and destroy various cells, from cancerous ones to kidney stones and fat cells.

In the case of liver tumors, the histotripsy method has become increasingly common, allowing for the non-invasive ablation of tumors, after which the body can manage the cleanup of the affected tissues. Histotripsy is a form of high-intensity focused ultrasound (HIFU) that employs continuous or pulsed waves to achieve the desired effect, utilizing a transducer equipped with an acoustic lens to establish a focal point. At this point, cavitation is induced, leading to the destruction of the local tissue.

Expectations are that, in addition to liver tumors, other tumors may also be treated similarly, which could be promising news, especially for solid tumors. Alongside new approaches, such as CAR T cell immunotherapy, the prospects for cancer treatment appear more optimistic than ever.
