Question

Research is being done on the use of radio waves in destroying cancer cells. What type of frequency would be best used in this technology? Justify your answer.

Answer 1

This is a John Kanzius Research. Radiofrequency Ablation (RFA) which is a type of Electrical Energy is used to treat cancer. It uses heat made by radio waves to kill cancer cells. Ablation means destroying completely. The method is putting RFA  a probe (electrode) that goes through the skin into the tumour. A CT scan is needed so to check that the probe is in exactly the right place. An electrode in the probe creates radiofrequency energy to produce heat and kill the cancer cells. 

Answer 2

Destroying cancer cells requires a lot of energy.

High-frequency waves have high energy.

--

The destruction of cancer cells requires a lot of energy, so high-frequency radio waves can be used in this technology because they have high energy.
