Ultrasound destroys cancer Science

Ultrasound-destroyed liver cancer cells did not recur in a recent study in rats. The form of treatment has also begun to be tried in humans.

A study at the University of Michigan ultrasound killed 50 to 75 percent of rat liver cancer cells.

The rat’s own immune system was then able to remove the rest of the cancer cells.

After treatment, more than 80% of the experimental animals showed no signs of cancer cell recurrence or metastasis.

Ultrasound kills cancer cells by producing small microbubbles in the cancer tissue, destroying the cancer cells mechanically.

The treatment has been developed at the University of Michigan for years. Now the bubbles produced by sound have been made to destroy cancer tissue accurately, even to the nearest millimeter.

“Even if we don’t destroy the entire tumor, we get the tumor to shrink and reduce the risk of metastasis,” commented the professor who performed the experiment. Zhen Xu University of Michigan in the bulletin.

Xu is a professor of biomedical engineering at the University of Michigan. He wrote the research report for the experiment, which he published scientific journal Cancers.

He does not promise a quick rescue from cancer. It is often not possible to treat the entire cancer with such treatment. The results are affected by the size, location, and stage of cancer growth.

People are slowly starting to try out new technology.

In the United States at a hospital in Miami last December, a 72-year-old patient’s tumor was destroyed by strong ultrasound pulses in the liver.

Sounds were directed at cancer cells from outside the body. Doctors were able to monitor in real time how the treatment destroyed the cells.

The prognosis for liver cancer treatments is still poor. In the United States, for example, less than 18 percent of patients live five years after liver cancer is diagnosed.
