<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.
