Early detection methods for prostate cancer Detection methods for prostate cancer

Prostate cancer is a common and multiple malignant tumor in men. Its incidence rate increases with age, and the peak age is between 70 and 80 years old. There are many causes of prostate cancer, such as age, genetics, diet, infection, endocrine system, etc., which affect all aspects of male patients. So what are the early detection methods for prostate cancer?

There are many methods for early detection of prostate cancer. The first one is digital rectal examination, which is a very important diagnostic method. Digital examination shows that the prostate capsule is irregular and a hard, stone-like lump can be felt, indicating the possibility of prostate cancer. If the seminal vesicle is affected, it is highly suspicious. The size of the lump varies, so it needs to be differentiated from prostate tuberculosis and stones. The accuracy of digital rectal examination can reach 50 to 70 percent.

The second test is the serum acid phosphatase measurement, which is performed 24 hours after the rectal examination and urethral examination. Eighty percent of prostate cancer patients with distant metastasis have elevated acid phosphatase, while 20% of patients without distant metastasis have elevated acid phosphatase. Therefore, a significant increase in serum acid phosphatase indicates that the patient may have prostate cancer.

The third examination is imaging examination, which can be done by X-ray examination. Observation of the patient's pelvis and lumbar spine radiography is an important means of diagnosing whether the cancer has metastasized. Sometimes seminal vesiculourethrography can also be performed. Cystourethrography of prostate cancer will show a lack of normal prostate curve, accompanied by urethral stiffness and stenosis. If the bladder is invaded, irregular filling defects can be seen at the bottom of the bladder. B-ultrasound examination can also be used to detect changes in prostate morphology and displacement, as well as discontinuous and rough capsule reflections. Light clusters and dark areas will appear inside the gland, which can be used as auxiliary diagnosis.

The fourth examination is the biopsy. The absolute diagnosis of prostate cancer depends on microscopic examination of tissue, so suspected patients should undergo perineal rectal puncture and biopsy. Before local spread and distant metastasis occur, when there are only signs of local nodules, biopsy can make an early diagnosis. The accuracy of diagnosis can reach 70 to 80 percent, which is currently the most reliable method for diagnosing prostate cancer.

These are the early detection methods for prostate cancer, so patients who suspect they have prostate cancer should go to the hospital for examination as soon as possible. The earlier the prostate cancer is, the greater the hope of cure. However, before the diagnosis is confirmed, patients should not put too much psychological pressure on themselves, as this will bring about bad consequences.
