Mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.
<h3>What is mechanical wave?</h3>
A mechanical wave is a wave that requires material medium for its propagation, example include;
- water waves,
- sound waves, and
- seismic waves.
<h3> Mechanical waves in treatment of cancers</h3>
Sound wave in example of mechanical wave because it requires material medium for its propagation.
High-frequency sound waves (HIFU) is used in the treatment of cancer because the strong beam generates heat which is directed to a specific part of a cancer.
The heat generated destroys the cancer cells.
Thus, mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.
