What are the early symptoms of male bladder cancer

Bladder cancer is the most common cancer in the urinary and reproductive system. Next, the editor will introduce the early symptoms of bladder cancer. Through these early symptoms, you can find, diagnose and treat it in time, which can play a preventive role to a certain extent. Come and read the following.

Early symptoms of bladder cancer

1. Hematuria

The most common symptom of bladder cancer is hematuria, which is visible to the naked eye without any feeling. This is a unique "abnormal urination signal" of bladder cancer. Almost every bladder cancer patient will experience it, and about 85% of bladder cancer patients seek medical treatment for this reason.

There are two types of hematuria: macroscopic hematuria and microscopic hematuria. Macroscopic hematuria refers to bloody urine that can be seen with the naked eye, while microscopic hematuria refers to red blood cells that can be found in the urine under a microscope.

Bladder cancer hematuria is mostly painless and intermittent. Most cases are full-course hematuria, while a few are terminal hematuria. Hematuria accompanied by frequent urination and urgency is less common.

2. Bladder irritation

Early stage bladder cancer rarely causes urinary tract irritation. If bladder cancer is accompanied by infection, or the tumor occurs in the trigone of the bladder, it will cause signs of urinary tract irritation. At the same time, the patient will have bladder irritation signs such as frequent urination, urgency, pain, and incomplete urination, indicating that he may have developed bladder carcinoma in situ.

3. Difficulty urinating

Some patients have symptoms of difficulty urinating, mainly deflected urine flow, slow urine flow, or even urine retention, due to the large size of bladder tumors, tumors growing in the bladder neck, or tumor bleeding and blood clots.

4. Frequent urination and urgency

If the tumor grows in the bladder triangle, bladder irritation may appear earlier, and if urinary pain occurs, it is no longer in the early stage. If urinary pain occurs suddenly and for unknown reasons, it is the earliest sign of bladder cancer.

5. Pain

If the tumor invades extensively and deeply, pain may occur, which is aggravated by bladder contraction and urine retention. If the tumor is located at the bladder neck, it may cause urethral obstruction and even urinary retention.
