Every day over eight weeks, the prostate is irradiated with a total dose of 76 Gy for a few minutes. More information can be found under radiotherapy.
An alternative to conventional radiotherapy is Brachytherapy. Here the prostate is treated with radioactive titanium pins the size of a grain of rice and thereby irradiated "from the inside". The procedure is minimally invasive and takes approx. 2 h. The patient is only hospitalised for two to three days. The results are comparable to those of conventional radiation, but the surrounding organs suffer less radiation.
