Seed implants provide high-dose radiation to the tumors without affecting healthy tissue surrounding the prostate. What's more, seed implants can be used in conjunction with external radiation therapy. Nevertheless, the simplicity of brachytherapy combined with its low risk make it an attractive choice for older patients whose prostate cancer is localized and who are not eligible for radical surgery. Watchful waiting is yet another treatment option. Some researchers recommend this approach because prostate cancer can grow very slowly in some men.
Early studies show no differences when compared to other treatment options.
A large VA Cooperative study on watchful waiting is being conducted and results of the study are eagerly awaited. African Americans and patients with a strong family history of prostate cancer are advised to begin screenings at age 40.
