Does anyone here know how many times in a 10 years period a person can have radiation?

Thanks a bunch,

Dana

For the Prostate only or anywhere on the body?

I'm mostly thinking of the prostate, but would like to know either. My bf will get radiation soon and I'm wondering if his psa still rises after that, how soon before he could have radiation again.

I believe they only do salvage radiation once. If PSA rises after that, it is presumed to have spread beyond local prostate area and is treated systemically, which in most cases means some form of androgen depravation therapy.

External radiation to the prostate can be done only once. Seeds can be done multiple times.

JohnT:

 

I did not know this about seeds being done multiple times.  Are you talking about permanent seeds such as I had or HDR?  And, not that I doubt you, but could you be kind enough to direct me to any literature on this possibility?  I tried googling "multiple prostate brachytherapy treatments" and "repeat prostate brachytherapy treatments" and could not find anything related to multiple seeding.

 

Thanks,

Hi Dana,

Sorry to hear about your boy friend. I had IMRT as my primary treatment and was told that this could not be repeated in the future. This is due primarily to the danger of over radiating the surrounding areas. Rectum, bladder and so on. The dose delivered to the prostate is lethal. The radiation machine delivers the dose from several points around the patient. This is done to limit the dose to adjacent organs to prevent radiation damage.

Thanks, I really appreciate the information and the time to respond.

Hang in there hugs to all,

Dana
