Prostate cancer detection

Early diagnosis of prostate cancer experts believe that the current symptoms of prostate cancer, the diagnosis of clinical symptoms and signs of prostate cancer is very important. If the disease has developed to the late stage. Therefore, for elderly men, regular investigation of early detection of small lesions and timely treatment can achieve good treatment results.

1. Rectal examination: Rectal examination is the main method for diagnosing prostate cancer. 80% of patients can be diagnosed. Rectal examination of prostate cancer is manifested by enlarged glands, hard nodules, unevenness, disappearance of the central groove, and fixed glands.

2. Acid phosphatase assay: Serum acid phosphatase is elevated in patients with prostate cancer. However, the specificity is not high. Some scholars have used immunoelectrophoresis to enhance sensitivity and detect prostate cancer at an early stage.

3. Prostate-specific antigen (pSA) is currently considered to have a higher diagnostic value than serum acid phosphatase.

4. Prostate puncture biopsy: In recent years, rectal B-ultrasound-guided puncture biopsy has been used. The accuracy has been greatly improved, which is of great significance for the diagnosis of early prostate cancer.

5. B-ultrasound examination:

B-ultrasound examination can detect changes in the shape and displacement of the prostate, discontinuous and non-lubricated capsule reflection, and light clusters and dark areas inside the gland. It can be used as an auxiliary means for the diagnosis of prostate cancer. This examination is non-invasive. Rectal ultrasound can clearly show subtle changes in the prostate and can confirm lesions with a diameter of 5 mm.

6. X-ray examination:

Pelvic and lumbar spine radiography is an important diagnostic tool for tumor metastasis and can sometimes be used for vas deferens and seminal vesiculography. For prostate cancer, cystourethrography shows a lack of normal prostate curves, coupled with a blunt urethral orifice stenosis. When the bladder is invaded, irregular filling defects can be seen at the base of the bladder.

7. Ultrasound examination:

Ultrasound examination can reveal changes in the shape and displacement of the prostate, discontinuous and non-lubricated capsule reflection, and light masses and dark areas inside the gland, etc. It can be used as an auxiliary diagnosis.

8. CT and MRI examinations:

The images are clear, the resolution is high, and it is safe and painless. This method of diagnosing prostate cancer has certain value.

Prostate cancer examination is very important, patients can take full advantage of modern technology, patients can understand their situation. In order to achieve the best treatment effect, make enough psychological preparation and face the disease positively. With the development of medical technology, more and more treatment methods have emerged, so patients should not lose hope, as long as the treatment is good, the disease can be significantly improved.
