[|Human|] I ve just read the article about higher incidence of bladder and rectal cancer for patients who have previously undergone radiation treatment for prostate cancer. I was diagnosed with bladder cancer in April 2013 (T1G3) and had the tumor removed via TURBT in May 2013. Cancer had advanced into my left ureter so I underwent more invasive abdominal surgery (partial ureterectomy) in June 2012. Had 6 BCG treatments in July and August and received all clear cystoscopies in October and January. PSA test in January showed irregularities (especially having only 7% free PSA) so underwent prostate biopsy in early February. Results showed cancer in 7 of 12 samples with a Gleason score of 7. One sample showed cancer was very near external wall of prostate. Had 28 external beam radiation treatments and 2 high dose radiation temporary brachytherapy treatments in March and April. I m having my first cystoscopy since early January on Monday, June 30. What s the likelihood of bladder cancer recurrence with the abdominal radiation I ve been through. Thanks!
[|AI|]  HelloThanks for your queryAlthough you have given detail information but still timeline events are not clear to me. But to answer your main query - chances of bladder cancer post radiation therapy for prostate cancer are very very very rare that too radiation induced cancer takes years to develop more than 10 years minimum. Either you have double malignancy one of bladder and other of prostate cancer which can be clarified by seeing the details of biopsy reports. Or you have primary malignancy of prostate which was missed earlier and had spread to bladder which is just located in front of and above prostate. Hope this helps.
