How will Radiotherapy affect me and how often is it required?

Following a radicle prostatectomy 5 years ago in Harley St., my follow ups have taken place under the
NHS locally.

My PSA has recently risen from 0.1- 0.2, 6/12 ago, and now has risen again to 0.3. (asymptomatic) (2 consecutive rises).
My routine follow up consultation has highlighted that this may require radiotherapy, - (oncologist to be contacted by registrar for his opinion)

What form does radiation at this stage normally take?
Will it require time off work... other than for the treatment itself and is this is advised?

Your PSA is slowly rising five years after radical prostatectomy. If an MRI scan of the pelvis shows no disease outside the prostate bed then I agree that radiotherapy is indicated. This would take approximately 7 weeks with you attending every weekday a radiotherapy department (each treatment taking about 15 minutes). It would be quite possible to continue your work during this time. The side effects would be urinary and rectal, should be mild and only affect you in the last week of treatment.
