Chronic prostatitis can certainly be difficult to treat. To answer your questions:
1) There is no specific studies showing a treatment to "strengthen" the immune system. I am not aware of vitamins that have been shown to help in consensus studies.
2) I am not aware of studies showing a definitive correlation between chronic prostatitis and prostate cancer.
These questions should be discussed with your personal urologist.
If the symptoms continue, a transrectal ultrasound can be considered to image the prostate for any abscesses.
Followup with your personal physician is
