Several major clinical manifestations of prostate cancer What are the diagnostic criteria for prostate cancer

Prostate cancer usually originates from the peripheral zone of the prostate gland, has a relatively hidden onset, and grows relatively slowly, so early prostate cancer may not have any warning symptoms, except for the elevated serum pSA value and abnormal prostate changes found during rectal examination. Once symptoms appear, it is usually a more advanced progressive prostate cancer.

Due to the aging population in my country, the incidence rate has increased in recent years. At the same time, due to the continuous improvement of diagnostic methods for prostate cancer, such as radioimmunoassay of acid phosphatase, determination of lactate dehydrogenase in prostatic fluid, transrectal ultrasound imaging, CT examination and improvement of prostate puncture needles, etc.

Common symptoms of prostate cancer

1. There are no symptoms in the early stage. When the cancer causes obstruction of the bladder neck and posterior urethra, symptoms may appear. Hematuria is less common. Some patients seek medical treatment for metastatic symptoms, such as back pain, sciatica, etc. Therefore, prostate cancer should be excluded for male metastatic cancer with unknown primary lesions.

2. There are big differences, which are related to the tumor classification. Latent and latent types have no local symptoms. The local symptoms of clinical type are similar to those of prostate hyperplasia.

3. Invasion of the urethra behind the bladder and neck, with symptoms of urethral stricture, inflammatory symptoms, frequent urination, urgency, pain, hematuria and difficulty urinating.

4. The patient has symptoms of chronic wasting, including weight loss, weakness, and anemia.

Specific symptoms of prostate cancer

1. Pain

Pain in the lower back, sacrum, buttocks, hips, pelvis, and sciatica is the most common and severe symptom of prostate cancer.

2. Metastatic symptoms

Metastasis is common in prostate cancer patients. About two-thirds of patients have lymph node metastasis when they first see a doctor. Symptoms of prostate cancer often occur in the iliac, iliac, waist, groin and other parts of the body. It can cause enlarged lymph nodes in the corresponding parts and swelling of the lower limbs.

3. Urinary dysfunction

Difficulty urinating, thinning or deflected urine stream, bifurcated urine stream, prolonged urination, frequent urination, urgency, pain when urinating, and a feeling of incomplete urination are all symptoms of prostate cancer. In severe cases, urine dripping and urinary retention may occur.

4. Systemic symptoms

Because the pain affects the diet, sleep and spirit, after long-term torture, the whole body condition becomes weaker and weaker, and the patient suffers from progressive anemia, cachexia or renal failure. This is one of the more serious symptoms of prostate cancer.
