What are the early diagnosis methods for prostate cancer? What tests are needed to diagnose prostate cancer?

What are the measures for early diagnosis of prostate cancer? The occurrence of prostate cancer can cause serious harm to men's health. If it is not discovered and treated in time in the early stages of prostate cancer, it will lead to male infertility. Therefore, it is very important for male friends to master the measures for early diagnosis of prostate cancer. For this reason, today we follow the editor to have the most detailed understanding and knowledge.

Early diagnosis of prostate cancer:

1. Rectal examination

Digital rectal examination is the main method for diagnosing early-stage prostate cancer. Because the prostate gland is close to the front of the rectum, the size and texture of the prostate gland can be felt through digital rectal examination. The normal prostate gland is about 4 cm to 3 cm in size, soft in texture, smooth in surface without nodules, and symmetrical on both sides. When a patient has prostate hyperplasia, the doctor can find changes in his prostate gland through digital rectal examination (the volume of the prostate gland will increase, but the texture will not be very hard). If the patient has prostate cancer, the doctor can feel the protruding tumor nodules on the surface of the prostate gland through digital rectal examination (if the tumor is large, the texture of the entire prostate gland will become very hard, like a stone).

2. Transrectal Ultrasound

Through transrectal ultrasound examination, doctors can find out whether there are nodules in the patient's sentinel gland. When nodules appear in the sentinel gland, but the nodules are small, or the nodules are inside the gland, they are often not felt through rectal digital examination. However, through transrectal ultrasound examination, such abnormal nodules can be found, so that sentinel gland cancer can be discovered early. In addition, 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 sentinel gland, which is very helpful in the treatment of sentinel gland cancer.

3. Serum sentinel gland specific antigen determination

Prostate-specific antigen is currently the most active marker of prostate cancer. Although prostate-specific antigen can also be detected in the blood of normal people, when the serum prostate-specific antigen increases to a certain value, it indicates that cancer cells exist in the patient's prostate. A study found that among the 473 patients who were eventually diagnosed with prostate cancer after serum prostate-specific antigen testing, 40% of the patients were not found through rectal examination. At present, due to the widespread clinical application of serum prostate-specific antigen testing, the diagnosis time of prostate cancer 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.

The editor has given a very detailed description of the early diagnosis of prostate cancer, and the early diagnosis of prostate cancer introduced above is also highly valued and recognized by many urologists in China. It is the best method for diagnosing prostate cancer in its early stage. However, it is necessary to remind all male friends that they must choose a regular men's hospital when conducting the above examinations.
