What are the common diagnostic methods for prostate tumors?

The early symptoms of prostate swelling are not obvious and are often mistaken for prostate hyperplasia. So, what are the common diagnostic methods for prostate tumors? Below we introduce them in detail and hope they can be helpful to you.

Prostate cancer is a disease that is difficult to detect in its early stages. Even if the malignant tumor in the prostate grows to a certain extent and compresses the urethra, it will only cause non-specific symptoms such as dysuria, hematuria, and acute urinary retention, which are often considered to be manifestations of prostate hyperplasia. Because of this, many patients are often in the late stages of their disease when they are diagnosed with prostate cancer.

1. Serum prostate-specific antigen determination. Prostate-specific antigen is currently the most sensitive marker for diagnosing prostate tumors. Although prostate-specific antigen can also be detected in the blood of normal people, when serum prostate-specific antigen rises to a certain value, it indicates that cancer cells exist in the patient's prostate. A study found that among 473 patients who were eventually confirmed to have prostate tumors after serum prostate-specific antigen determination, 40% of the patients were not found through rectal digital examination. At present, due to the widespread clinical application of serum prostate-specific antigen determination, the diagnosis time of prostate tumor patients has been advanced by an average of 5 to 8 years, which provides more time and opportunities to save the lives of patients with the disease.

2. Rectal examination: Rectal examination is one of the common diagnostic methods for prostate tumors. Since the prostate is close to the front of the rectum, the size and texture of the prostate can be felt through rectal examination. The normal prostate gland is about 4 cm x 3 cm in size, soft in texture, smooth on the surface without nodules, and symmetrical on both sides. When a patient has prostate hyperplasia, the doctor can find changes in his prostate gland through rectal examination (the volume of the prostate will increase, but the texture will not be very hard). If a patient has a prostate tumor, the doctor can feel the protruding tumor nodules on the surface of the prostate through rectal examination (if the tumor is large, the texture of the entire prostate will become very hard, like a stone).

3. Transrectal ultrasound examination: Through transrectal ultrasound examination, doctors can find out whether there are nodules in the patient's prostate. When nodules appear in the prostate, but the nodules are small or they grow inside the gland, they are often not felt through rectal examination. However, through transrectal ultrasound examination, such abnormal nodules can be found, so that prostate tumors can be discovered early. Moreover, through transrectal ultrasound examination, doctors can also determine the size of the patient's tumor and whether the tumor has invaded the capsule of the prostate, which is very helpful for the treatment of prostate tumors.

The above is a brief introduction to the common diagnostic methods for prostate tumors. It reminds male friends to take preventive measures as early as possible to avoid the occurrence of prostate tumors.
