Abstract: This study summarizes up-to-date information about the biopositive effects of low radiation treatment (LRT), radiation hormesis, and our experimental devices. In addition, we present a favorable treatment result in a patient with advanced rectal carcinoma who received LRT at home using a radon gas aspirator. The patient was a 61-year-old man who underwent proctectomy in 2010. During the additional first-line chemotherapy, apparent increases in tumor makers identified multiple remote metastases in the lung, sacrum and liver. Sacrum pain limited his activity of daily living and impeded his coming to our facility for LRT. Then, we decided to provide him home LRT using a radon gas aspirator. He inhaled radon gas for 15 minutes at least 3 times a day at home, resulting in remarkably reduced tumor markers and sacrum pain relief. He could walk, keep sitting up without support and sleep in the spine position again after receiving home LRT. No influence of radon gas inhalation on the second-line chemotherapy was observed. The favorable effects of LRT lead us to believe that the newly-developed devices will provide the clinical significance on malignant diseases. To establish the LRT regimen, further clinical investigation and data accumulation are thus called for.
