Is it better to have prostate removed or radiation?
Radiation may be a better choice for men who want to avoid the side effects of surgery, such as leaking urine and erection problems. It may be a better choice for men who have other health problems that make surgery too risky. You avoid the risks of major surgery.
Can you be around someone with radiation seeds?
With permanent brachytherapy, the source, such as radioactive seeds, stay in place forever. But the radiation gradually disappears over several weeks or months until the source is no longer radioactive. The radiation doesn't travel very far from the treatment area. So it is usually safe to be with other people.
