The answer is D. Transrectal prostate biopsy
Prostate cancer is the most common cancer among men (excluding skin cancer) — as about 1 in 8 men will get it. The most important risk factor for the development of prostate cancer is increasing age. Other risk factors include ethnicity, genetic factors, obesity, tobacco, and a diet high in animal fat. Clinical manifestations may include non-specific urinary symptoms (frequency, urgency, etc), hematuria, bone pain, elevated PSA, and an indurated/asymmetrical prostate with nodules on digital rectal exam. A transrectal prostate biopsy will confirm the diagnosis of prostate cancer.
