Digital rectal examination is very important for the diagnosis of early prostate cancer

As the incidence of prostate cancer has been increasing year by year in recent years, the diagnosis of prostate cancer is very helpful for the treatment of the disease. Experts say that the diagnosis of prostate cancer is mainly based on metastatic symptoms. What are the diagnostic methods for prostate cancer? The following is an introduction to the diagnosis of prostate cancer.

1. Serum prostate-specific antigen determination:

The diagnosis of this type of prostate cancer should be performed one week after rectal examination and urethral diagnosis. Prostate-specific antigen is a more sensitive tumor marker than acid phosphatase, and is of great significance for the diagnosis, clinical staging, efficacy observation, prognosis determination and recurrence monitoring of prostate cancer.

2. X-ray diagnosis:

Pelvic and lumbar spine radiographs are important for determining whether the cancer has metastasized. Sometimes, vasoconstriction and cystourethrography can also be performed. Cystourethrography of prostate cancer shows a lack of normal prostate curves, accompanied by urethral stiffness and stenosis. When the bladder is invaded, irregular filling defects can be seen at the bottom of the bladder.

3. Rectal examination:

Rectal examination is very important for the diagnosis of early prostate cancer. It can be manifested as irregular prostate capsule and palpable hard stone-like masses. If it involves the seminal vesicle, it is highly suspicious. The masses vary in size, and the diagnosis of prostate cancer should be distinguished from prostate tuberculosis and stones.

4. Acid phosphatase assay:

The diagnosis of prostate cancer should be performed 24 hours after rectal examination and urethral examination. 20% of patients without distant metastasis have elevated acid phosphatase. Therefore, a clear increase in serum acid phosphatase indicates the possibility of prostate cancer.
