What are the symptoms of prostate tumors?

Prostate tumors may have no obvious symptoms in the early stages. As the disease progresses, symptoms such as difficulty urinating, hematuria, pelvic area pain, erectile dysfunction, and bone pain may occur. Symptoms of prostate tumors mainly include abnormal urination, local pain, sexual dysfunction, systemic symptoms and metastasis symptoms.

1. Abnormal urination

Prostate tumors may cause difficulty urinating, thin urine stream, frequent urination and urgency, especially increased nocturia. When the tumor enlarges and compresses the urethra, it will cause interruption of urination or a feeling of incomplete urination. In severe cases, acute urinary retention may occur. In some patients, initial hematuria or terminal hematuria may be seen, and the urine is light red or watery.

2. Local pain

When tumors invade the prostate capsule or surrounding tissues, they can cause persistent dull pain in the perineum and lower abdomen. In some patients, the pain radiates to the lumbosacral region. Late-stage patients may experience sciatica-like symptoms due to nerve compression, with pain worsening when sitting for long periods of time or when defecating.

3. Sexual dysfunction

When tumors involve the neurovascular bundles that control erection, erection or maintenance difficulties may occur. Some patients are accompanied by reduced semen volume or painful ejaculation, which is related to seminal vesicle invasion or vas deferens obstruction. It is important to note that these symptoms may also be confused with benign prostatic hyperplasia.

4. Systemic symptoms

In the progressive stage of the disease, unexplained weight loss, persistent low-grade fever, anemia and other depleting manifestations may occur. This is related to active tumor metabolism consuming body nutrients or the release of chronic inflammatory factors. Some patients will experience edema of both lower limbs, suggesting that lymphatic drainage may be blocked.

5. Metastasis symptoms

When bone metastasis occurs, it presents as fixed pain in the spine, pelvis, or ribs that is worse at night and poorly responsive to common analgesics. Lung metastasis can cause chronic cough and hemoptysis, and liver metastasis can cause dull pain in the right upper quadrant or jaundice. Some patients develop weakness or abnormal sensation in their lower limbs due to spinal cord compression.

Regular prostate-specific antigen screening is recommended, especially for men over 50 years old or those with a family history. If symptoms of abnormal urination or pelvic pain occur, you should seek medical treatment promptly, avoid excessive intake of high-fat diet, and maintain moderate exercise. Diagnosis and treatment require clear staging through digital rectal examination, imaging examinations, and pathological biopsy. Treatment plans should be individualized based on age, underlying diseases, and tumor characteristics.
