Main Answer:
A digital rectal examination can allow the clinician to diagnose prostate cancer.The option A is correct.
Explanation:
A digital rectal examination (DRE) is a physical examination that involves the insertion of a gloved finger into the rectum to assess the size, shape, and texture of the prostate gland.
This assessment can provide important information about the health of the prostate and may help clinicians diagnose certain conditions, including prostate cancer.
Prostate cancer is a type of cancer that affects the prostate gland, which is located near the rectum in men. In its early stages, prostate cancer may not cause any symptoms, making it difficult to detect.
However, as the cancer grows, it can cause a variety of symptoms, including difficulty urinating, blood in the urine or semen, and bone pain.
During a DRE, the clinician can feel any abnormalities in the prostate gland, such as lumps or hard areas, which may indicate the presence of cancer.
he size and texture of the prostate can also provide clues about the stage and severity of the cancer. In addition to a DRE, other diagnostic tests may be necessary to confirm a diagnosis of prostate cancer, such as blood tests to measure levels of a protein called prostate-specific antigen (PSA) or imaging studies to assess the extent of the cancer.
In summary, a digital rectal examination can be an important tool for diagnosing prostate cancer, as it allows clinicians to assess the health of the prostate gland and identify any abnormalities that may indicate the presence of cancer.
However, it should be noted that other conditions, such as benign prostatic hyperplasia (BPH) and prostatitis (inflammation of the prostate), can also cause changes in the size and texture of the prostate gland during a DRE, so additional diagnostic tests may be necessary to confirm a diagnosis.The option A is correct.
