What are the criteria for checking prostate cancer

The occurrence of prostate cancer is mainly related to factors such as age, race, family genetic background, geographical location and dietary structure. The incidence of prostate cancer varies greatly worldwide, and the incidence in Asians is much lower than that in Europeans and Americans. In the United States, the incidence of prostate cancer ranks first among all male malignant tumors, and the mortality rate ranks second only to lung cancer. So what are the criteria for checking for prostate cancer?

1. Simple and effective early diagnosis method Rectal digital examination Rectal digital examination is very important for early diagnosis of prostate cancer. If the prostate capsule is irregular and a hard stone-like mass can be felt, it is suspicious; if it involves the seminal vesicle, it is highly suspicious. The mass varies in size and should be differentiated from prostate tuberculosis and calculi.
2. Serum acid phosphatase determination This test should be performed 24 hours after rectal examination and urethral examination. The acid phosphatase level of prostate cancer patients with distant metastasis is elevated, and that of patients without distant metastasis is elevated. Therefore, a significant increase in serum acid phosphatase indicates the possibility of prostate cancer.
3. Serum prostate-specific antigen (PSA) measurement This test should be performed one week after rectal examination and urethral examination. 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 judgment and recurrence monitoring of prostate cancer.
