Final answer:
It is true that a needle biopsy of the prostate can be performed using a transrectal approach, which is an essential step in diagnosing prostate cancer through microscopic examination of prostate tissue.
Step-by-step explanation:
True, a needle biopsy of the prostate can indeed be accomplished with a transrectal approach. This procedure is typically performed when there is a suspicion of prostate cancer, which may initially be detected through a physical exam or a high level of prostate-specific antigen (PSA) in the blood. If a lump is found on the prostate or elevated PSA levels are present, a biopsy is required for definitive diagnosis. During this procedure, a small sample of prostate tissue is obtained using a needle inserted through the rectum. The extracted tissue is then examined microscopically for cancer cells.
Prostate cancer is usually diagnosed in later life and can often be slow growing, with some cases not requiring immediate treatment. However, in younger patients or those with faster-growing tumors, more aggressive treatment including surgery, chemotherapy, and/or radiation therapy may be necessary.
