Hello sir, I was hospitalized due to high fever and urine infection as I was not able to urinate properly. Upon ultrasound diagnosis, we found 50% blockage of urinary tract which lead to urine infection and high fever. Was treated for that and during that time, I also understand psa total diagnosis the result of which were quite disappointing as the levels of psa antigen have risen to 56.8 whereas the normal range is below 4. The doctors were sensing that it could be a sign of prostate cancer as I was treated for prostate laser therapy in the past as well (2005) when there were increased prostate that were treated by laser therapy. Please suggest if this is a sign of cancer and what are the next steps. Thanks in advance.
