Q
Why doesn't the radiation damage other organs?
One of the special features of radioactive seeds is that its radiation does not spread very far. In fact, one centimeter from the seed the radiation level drops off dramatically. This allows us to position the seeds so they do not have a major effect on neighboring tissue and organs. Q Is it safe to have a source of radiation inside the body? Another feature of the seeds is that they lose their radioactive power very quickly. It runs down like a battery. Approximately four months after the procedure, they no longer give off radiation. The seeds do not have to be removed after the procedure. Q Is it painful? This procedure is done on an outpatient basis using a spinal or general anesthetic. The whole procedure takes from 45 minutes to one hour. Patients are back to normal activities within a day or two. Q What are the side effects? With seed implants, impotence occurs in about 10 to 15 percent of the cases and incontinence is a true rarity. In contrast, when treatment requires surgical removal of the prostate gland, the man's potency often suffers and up to 20 percent may experience some degree of incontinence. Q Can anyone with prostate cancer have this treatment? This treatment is used as the sole modality for those patients who have been diagnosed as having early stage prostate cancer. For those with more advanced stages of the disease, seed implants are typically used in conjunction with other types of treatment (for example, a short course of 3-D radiation, hormones, etc.). |
