How is prostate cancer diagnosed? What tests should prostate cancer patients undergo?

Nowadays, it is generally not difficult to diagnose prostate cancer. Some common examination items can basically achieve the purpose of diagnosis. There is a relatively obvious high-risk group for prostate cancer. It is recommended that this group of people pay attention to physical examinations, so as to prevent and detect prostate cancer in time. The following is an introduction to the diagnosis of prostate cancer:

1. Digital rectal examination

Careful rectal examination is important for the diagnosis and staging of prostate cancer.

(ii) Ultrasound examination

It is beneficial for the early diagnosis and efficacy observation of prostate cancer.

3. Laboratory examination

1. Blood acid phosphatase. About 70% of prostate cancer patients have elevated blood acid phosphatase.

2. Tests such as blood alkaline phosphatase, lactate dehydrogenase, carcinoembryonic antigen and prostate-specific antigen lack specificity and are only used for screening tests.

(IV) Pathological examination

1. Transrectal needle aspiration cytology.

2. Transperineal needle aspiration cytology examination.

3. Transrectal prostate puncture biopsy under ultrasound, this method is more accurate.

(V) Further

1. Take a bone X-ray to see if there is any metastasis.

2. Urinary tract angiography to understand the condition of the upper urinary tract and local lesions.

3. CT and MRI examinations are helpful for staging local tumors.

4. Lymph node resection and pathological examination to understand the stage and determine the treatment plan.

One thing you must know is that prostate cancer can cause great damage to the patient's body. After diagnosis, it is often the progressive stage of the disease. The progressive stage of malignant tumors is generally incurable, and the same is true for prostate cancer. Therefore, it must be discovered in time.
