Prostate cancer can range from stage 1 to 4. There is no stage 6/7. Please confirm stage. I guess you are talking about Gleason score which can range from 2-10. It is grade of tumor done from biopsy specimen. After diagnosis, he needs to undergo complete evaluation to find stage of disease. Evaluation include MRI of pelvis, Bone scan, blood PSA level to find how far the tumor has spread and treatment will depend on accordingly. Radiation(not Radium) and surgery are equally effective treatment option for this cancer. There are risk and benefit of both treatment and choosing one depends on different factors like age, stage of disease and preference of patient. If cancer is early stage active surveillance(wait and watch) is also a treatment option. Discuss with your urologist and oncologist regarding these options Regards </s>
