### Patient: Doctor, I recently noticed some changes in my urinary habits and I am experiencing difficulty in passing urine with blood. I am worried I might have prostate cancer. 
### Doctor: Based on your symptoms, we need to conduct a few medical tests to determine the underlying condition. We need to perform a prostatic specific antigen measurement, a rectal examination, ultrasonography, urinalysis, and a biopsy in order to diagnose if it is indeed prostate cancer. Additionally, we also need to conduct hematologic tests and other diagnostic procedures to assess your overall health and evaluate any other underlying issues.
