What are the early symptoms of bladder cancer?

Bladder cancer is a common male urinary disease with a high incidence rate. We can detect bladder cancer in time by observing its early symptoms. So what are the early symptoms of bladder cancer ? The following is a detailed answer from relevant experts.

1. 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. In short, if unexplained urinary pain suddenly occurs, it is the earliest sign of bladder cancer.

2. Pain

If the tumor invades widely 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. If the tumor invades the urethral orifice, hydronephrosis and ascending infection may occur. Severe patients may develop sepsis and uremia. Cachexia may occur in the late stage, which is one of the early symptoms of bladder cancer.

3. 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 eyes, 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 of which is full-course hematuria, and a few are terminal hematuria. Hematuria accompanied by frequent urination and urgency is rare.

The above is an introduction to the early symptoms of bladder cancer. I believe everyone should have a certain understanding of bladder cancer. If you want to know more about bladder cancer, please consult online experts.
