RATIONALE: Genistein may increase the effectiveness of radiation therapy in treating pain caused by bone metastases.
PURPOSE: This phase I/II trial is studying the side effects of genistein and to see how well it works in treating patients undergoing external-beam radiation therapy for pain caused by bone metastases.

|Breast Cancer Kidney Cancer Lung Cancer Melanoma Metastatic Cancer Pain Prostate Cancer||Dietary Supplement: genistein Radiation: radiation therapy||Phase 1 Phase 2|
- To determine whether genistein is safe when administered in combination with palliative external beam radiotherapy in patients with osseous metastases.
- To determine the time to pain relief, duration of pain relief, and degree of pain relief in patients treated with this regimen.
- To determine the incidence of pathologic fractures in patients treated with this regimen.
- To determine the effect of this regimen on quality of life measures in these patients.
OUTLINE: This is a multicenter study.
Patients undergo external beam radiotherapy once daily on days 1-10. Patients also receive oral genistein once daily on days 1-60.
Patients complete pain and quality-of-life questionnaires periodically.
After completion of study therapy, patients are followed at 30 days.
