Understand the main diagnostic methods of prostate tumors

In the diagnosis of prostate tumors, clinical symptoms and signs are the most important. If you can have regular physical examinations, you can find the disease early. Therefore, male friends should have a physical examination once a year. What are the main diagnostic methods for prostate tumors? Let's learn about it together.

1. CT examination: CT examination can determine the degree of infiltration of prostate tumors.

2. Rectal examination: Rectal examination is the main method for diagnosing prostate tumors. Diagnosis can be obtained in 80% of cases. Rectal examination of patients over 45 years old can detect prostate tumors at an early stage and increase the surgical rate.

3. Ultrasound examination: It can depict the cross-section of the prostate and reflect the extent of the lesion.

4. Microscopic examination: Urine smear to find prostate tumor cells. This method cannot replace prostate biopsy, but can only be used as an auxiliary method. Prostate fluid smear cytology is one of the main diagnostic methods for prostate tumors, and this method has a high accuracy rate (some reports say it can reach 86%). Leukocyte adhesion inhibition test. This test is recognized as a relatively simple and sensitive method for tumor antigen detection.

5. MRI examination: MRI examination can show the extent of lesions in the prostate and surrounding tissues.

6. Radionuclide scanning: often used to diagnose bone metastasis of prostate tumors.

7. Biochemical examination: acid phosphatase (PAP) determination; bone marrow acid phosphatase (BMAP) determination; prostate specific antigen (PSA); seminal plasma protein (r-Sm) determination; serum creatine kinase (CK-BB) determination; alkaline phosphatase determination; relative enzyme index; carcinoembryonic antigen (CEA); hormone receptor determination; immune protein analysis; lactate dehydrogenase isoenzyme (LDH) examination; urine polyamines (Polyaraine) determination; urine biochemical hydroxyproline determination; 14) Plasma zinc determination and vitamin A/zinc ratio.

After reading the above introduction, I believe everyone has a certain understanding of the main diagnostic methods for prostate tumors. I would like to remind everyone to do a good job of prevention in life to prevent the occurrence of diseases.
