Hi Kate,

When I had 37 sessions for my prostate, I didnt have hardly any side effects.The main ones are it can give you the runs but I took I moduim Instants and never had any problems. It can make you tired particulary towards the end of the treatment but I did as the nursed advised, If I felt tired I went and had a lie down for a short while. My wife bought some Simple soap as R/THERAPY  can sometimes make the skin very sore.  I never had any problem because of this. The main thing is to drink plenty of water before the treatment session. The nurses were always asking if I had drunk plenty of water and one day I replied if I were to drink anymore I would resemble a camel. Quick as as flash she replied a one hump or two hump camel ha ha. 

In some places they are now giving only about 20 sessions but a higher dose each time. They have found this results in the same level of treatment but with less side effects for the patient, which has to be good.

If I can help at all please feel free to ask. Best wishes to you and your dad, Brian.
