I am a fit and well 77yr old, a few years ago had a negative biopsy,a year later due to raised psa had a second biopsy and give me a Gleason score of 3+3 T1 . An mri scan showed a small increase in liaison in my prostrate and my psa is still raised. I have the option of radiotherapy. Should I stay on watchful waiting/ active surveillance or go for treatment. I am at the moment fit and well.
