Objective: To evaluate if urine radon can be a potential marker for cancers other than lung cancer.
Materials and Methods: This was a cross-sectional study with the inclusion criteria were adult patients diagnosed as non-lung cancer or healthy control subjects and agreed to participate in the study. Urine Radon, an outcome of the study, was measured with the RAD 7 and compared between the groups of cancers other than lung cancer versus control group.
Results: There were 144 patients participating in the present study. Of those, 56 patients (38.19%) were control patients, 42 patients (29.17%) had gastrointestinal cancer, 8 patients (5.56%) had breast cancer, 12 patients (8.33%) had gynecological cancer, 13 patients (9.03%) had hematological cancer, and 14 patients (9.72%) had otolaryngology cancer. There were comparable results on age, body mass index, urine pH including urine radon among six groups. The median urine radon was highest in the control group and gynecological cancer group at 402 Bq/m3 (p=0.222).
Conclusion: Urine radon levels among various cancers other than lung cancer were not different from the control group. Further studies are required to confirm the results of the present study due to the small sample size.
