I am considering possibilities of hyperthermia like scenario to destroy cancerous tissues inside a human body using a swallowed pill. I am conserving solid-state devices like Gunn diodes or RTDs to generate local RF heating to achieve my goals. Your comments and guidance to existing technologies would be valuable. Thank you.
Ata: I am working under the assumptions that (1) H2O is the primary target material in both healthy and tumor tissue so that the RF absorption spectra is the same in both types of tissue, and (2) the temperature tolerance of both types of tissues is the same - i.e., elevated temperature damages healthy/sick tissue at the same rate. If that be the case, then the primary issue is beam focusing.
If instead the tumor is damaged at an elevated temperature while the healthy tissue is unaffected - then the problem would be greatly simplified, since an isotropic source would suffice to eliminate the diseased tissue.

Is your approach similar to HIFU? which was approved for early stage prostate cancer patients.
