What are the symptoms of prostate cancer

What are the symptoms of prostate cancer? Prostate cancer is a malignant tumor that is more common in men. The incidence rate gradually increases with age. Prostate cancer is often asymptomatic in the early stages, so it is easy to be ignored. As the tumor develops, the symptoms become more and more obvious. So, what are the symptoms of prostate cancer? Let's take a look.

1. Lower urinary tract symptoms: including irritation symptoms and obstruction symptoms. First of all, it should be clear that lower urinary tract symptoms are not unique to prostate cancer, but are more common in many benign urological lesions. In patients with prostate cancer, when the tumor infiltrates the front and middle part of the prostate, invades the urethra, bladder neck and trigone, it can cause lower urinary tract symptoms. These include frequent urination, urgency, hesitant urination, interrupted urination, dripping after urination and labored urination, etc.

2. Local invasive symptoms: When the tumor invades the prostate capsule and the nearby perineural lymphatic vessels, perineum pain and sciatica may occur. When the tumor invades and compresses the vas deferens, low back pain and testicular pain on the affected side may occur. When the tumor invades above the bladder-rectum space, it may compress the ureter and cause unilateral or bilateral hydronephrosis, which may cause renal failure in severe cases.

3. When the tumor invades the neurovascular bundle on the posterior and lateral sides of the prostate, it can also cause erectile dysfunction. In severe cases, when the tumor invades the rectum, it can cause difficulty in defecation or colon obstruction. When the tumor invades the membranous urethra, urinary incontinence may occur.

4. Metastatic symptoms: In the late stage of prostate cancer, patients will also experience some symptoms of metastatic cancer due to the metastasis of the tumor. About 1/3 or even 2/3 of patients have lymph node metastasis when they first see a doctor, mostly in the iliac, iliac, waist, groin and other parts. It can cause lymph node enlargement and lower limb swelling in the corresponding parts. Hematogenous metastasis is more common in bones such as pelvis, sacrum, lumbar spine, upper femur, etc. and internal organs such as lungs, liver, brain, adrenal glands, testicles, etc.

5. Systemic symptoms: Since prostate cancer patients will experience some systemic symptoms, such as pain, long-term pain will affect the patient's diet, sleep and spirit, making the patient's general condition gradually weak, followed by weight loss and fatigue, progressive anemia, and eventually develop into cachexia or renal failure.

It can be seen that the early symptoms of prostate cancer patients are atypical, and prostate cancer cannot be discovered through early clinical manifestations. When prostate cancer shows certain clinical symptoms, it is often in the late stage. Since the key to improving the treatment effect of prostate cancer is early diagnosis and early treatment, it is very important to do a good job in prostate cancer census and screening.
