Bladder cancer is the most common cancer in the genitourinary system. Next, we will introduce the early symptoms of bladder cancer. Through these early symptoms, you can detect, diagnose and treat it in time, which can play a preventive role to a certain extent. Let’s take a look below.
What is bladder cancer? Bladder cancer is the most common malignant tumor in the urinary system, and its incidence ranks first among all malignant tumors in the urinary system. The incidence of bladder cancer mostly occurs in middle-aged and elderly people over 50 years old, and the incidence rate increases with age. Early symptoms of bladder cancer I. Hematuria The most common symptoms of bladder cancer are Hematuria without any sensation and visible to the naked eye, which is a unique “abnormal urination signal” of bladder cancer and occurs in almost every bladder cancer patient, and about 85% of bladder cancer patients visit the doctor for this reason.
There are two kinds of hematuria, one is carnal hematuria and the other is microscopic hematuria. The first one is the visual hematuria, and the second one is the microscopic hematuria.
Bladder cancer hematuria is mostly painless and intermittent, most of them are whole hematuria, a few of them are terminal hematuria, and hematuria with frequency and urgency is less common.
Bladder irritation Early bladder cancer produces relatively little urinary tract irritation. If bladder cancer is also combined with infection or the tumor is found in the bladder triangle, it will lead to urinary tract irritation signs. At the same time, patients will produce bladder irritation signs such as frequent urination, urgent urination, painful urination and incomplete urination, which indicates that they may have developed bladder cancer in situ.
Difficulty in urination Some patients have difficulty in urination due to the large size of bladder tumor, tumor growth in the bladder neck, or tumor bleeding and blood clot, which leads to long-term obstruction of urine flow, and then patients will have difficulty in urination, mainly due to skewed urine flow, slow urine flow, or even urinary retention.
If the cancer grows in the bladder triangle, bladder irritation may appear earlier, and if painful urination occurs, it is not early. In a word, if unexplained painful urination suddenly appears, it is the earliest signal of bladder cancer.
Pain If the tumor invades widely and deeply, pain may appear and intensify during bladder contraction and urinary support. If the tumor is located in the bladder neck, it may cause urethral obstruction and even urinary retention.
If the tumor invades the ureteral orifice, hydronephrosis and episodic infection may occur. In serious cases, sepsis and uremia may be caused, and cachexia may occur in advanced stage.
