First of all let me express my gratitude for your military service, we all owe you and all our service men and women our heartfelt thanks!

I am not a physician, just a fellow PCa patient, who happens to know something about chemistry and research (retired chemical engineer).

I know about PFAS and a quick search found this document, which may relate directly to your situation and potential military exposure to AFFF.

In any case, my quick search indicates that one must have a positive diagnosis of PCa, if you are following up regarding your concern about AFFF exposure.

For better or worse, one cannot claim a PCa diagnosis unless a biopsy makes that finding positive.

As good as mpMRI’s have progressed, they are still not accepted as proof of diagnosis of prostate cancer in the US (if anyone reading knows otherwise, please indicate).

Therefore, if you’re pursuing action with the VA and AFFF exposure, regarding the possibility of PCa, a biopsy will be necessary.

Person to person, I hope you would be found to have no PCa, based on a biopsy and that it turns out only to be BPH and inflammation…certainly a possibility with the size of your prostate.

I’ll be remembering you in my prayers!

All the best!
