What are the early symptoms of prostate cancer?

Prostate cancer often occurs in the posterior lobe of the prostate. In the early stage, there are usually no symptoms. Even if there is some discomfort, the patient himself often thinks that he is old and it is normal to have some discomfort when urinating, so there is no need to make a fuss. When the tumor grows to a certain extent and compresses the urethra, causing difficulty in urination, it is often confused with symptoms such as dysuria caused by prostate hypertrophy. This makes patients delay going to the hospital for treatment, thus delaying the opportunity for early detection and treatment. As a result, most patients first find distant metastatic lesions, and after further examination, they find that the real culprit is actually prostate cancer. At this time, the lesion is already in the late stage, and the opportunity for radical treatment has been lost, and the prognosis is poor. In the United States, due to early detection, the survival rate of localized prostate cancer after surgery exceeds 90% ten years. It can be seen that only when prostate cancer is discovered early can effective and scientific treatment methods be adopted in time.

The appearance and severity of prostate cancer symptoms depend on the speed of tumor growth and the degree of urethral compression. Because the prostate encircles the urethra, the cancer will compress the urethra only after it has grown to a certain extent, showing symptoms of abnormal urination. Only a few people experience frequent urination and increased nocturia. When the tumor further increases and compresses the urethra, the urine flow will become thinner, urination will be difficult, and the urination process will be prolonged. A small number of patients may experience pain when urinating, and some may even have hematuria, which should be a cause for concern. When the tumor gradually grows, the urethra is more severely compressed, making urination difficult, causing urine to be retained in the bladder, and the bladder is filled and swollen, and even highly inflated, which is extremely uncomfortable. In addition, when prostate cancer metastasizes, especially when it metastasizes to the bones, low back pain may occur, and the pain can often radiate to the perineum and around the anus, and even paraplegia may occur.

Therefore, men over the age of 50 who have frequent urination, increased nocturia, prolonged urination, thinning urine flow, and difficulty urinating are often considered to be caused by prostate hyperplasia, but the possibility of prostate cancer should be considered and prostate cancer should be ruled out through examination. Men over the age of 50 should have a rectal examination and prostate-specific antigen (PSA) test at least once a year, which is extremely important for early diagnosis. The accuracy of rectal examination is 50% to 80%, which can be used to obtain early diagnosis so as to seize the opportunity for radical treatment. The clinical application of PSA testing methods developed in recent years has provided great convenience for improving the accuracy of prostate cancer diagnosis. This examination method can make a diagnosis by drawing a small amount of blood. In most cases, tumors can be found in the early stages of prostate cancer so that treatment measures can be taken in time.

If you find that your PSA level is elevated, you should consult a specialist to determine whether it is a possible prostate disease and whether further tests are needed. You must not be careless and delay early diagnosis.

In addition to rectal examination and blood test for PSA, transrectal B-mode ultrasound examination is commonly used in clinical practice. It can more accurately detect the internal structure of the prostate and reflect the scope of the lesion. For suspected patients, a small amount of prostate tissue should be obtained through perineal or rectal puncture for pathological examination. It has a high positive rate, less pain, fewer complications, can be performed in an outpatient clinic, and is currently the most accurate method for diagnosing prostate cancer. CT examinations can determine the degree of infiltration of prostate cancer, and magnetic resonance imaging (MRI) examinations can show the degree of lesions in the prostate and surrounding tissues. These examinations are helpful in the diagnosis and staging of prostate cancer. Radionuclide scanning examinations are often used to diagnose bone metastases of prostate cancer.

Is it possible for patients who have undergone surgery for prostate hyperplasia to develop prostate cancer? The answer is yes. Because prostate hyperplasia surgery, whether it is open surgery or transurethral resection, only removes the hyperplastic prostate adenoma, and the peripheral part of the prostate, which is most prone to prostate cancer, still exists, so there is still the possibility of malignant transformation and prostate cancer. Therefore, patients with benign prostatic hyperplasia still need to be vigilant about the possibility of prostate cancer after prostatectomy. Regular examinations are necessary, and when the PSA value is detected, you should be more vigilant and consider further examinations.
