What are the symptoms of bladder cancer

Common symptoms of bladder cancer include hematuria, frequent urination, urgency, and painful urination. Early symptoms may not be obvious, so you need to seek medical attention in time. Hematuria is the most typical symptom of bladder cancer. It is usually painless and intermittent. Frequent urination and urgency may be related to bladder irritation, while painful urination may indicate infection or tumor invasion. Early detection and treatment are the key to improving prognosis.

1. Hematuria is the most common symptom of bladder cancer. It is characterized by red or brown urine, which is usually painless and occurs intermittently. Hematuria may be visible to the naked eye or only found under a microscope. The presence of hematuria indicates that the bladder mucosa is damaged, which may be caused by ruptured blood vessels due to tumor growth. If painless hematuria occurs, you should immediately seek medical attention for further examination, such as urine routine, cystoscopy, and imaging examinations.

2. Frequent urination and urgency are common symptoms of bladder cancer. Patients may feel the need to urinate frequently, but the amount of urine urinated each time is small. Urgency is manifested as a sudden and strong desire to urinate that is difficult to control. These symptoms may be related to bladder tumors irritating the bladder wall, resulting in reduced bladder capacity or overactive bladder. If frequent urination and urgency persist, urinalysis and bladder function tests are recommended to rule out other possible causes.

3. Painful urination is another common symptom of bladder cancer. Patients may feel pain in the urethra or bladder area when urinating. The pain may be related to the invasion of the bladder wall by the tumor or a concurrent urinary tract infection. Painful urination may also be accompanied by urinary tract irritation symptoms such as urgency and frequency of urination. If painful urination occurs, you should seek medical attention in time for urine culture and cystoscopy to determine the cause and develop a treatment plan.

4. Other symptoms include lower abdominal pain, weight loss, and fatigue. Lower abdominal pain may be related to the invasion of surrounding tissues or lymph nodes by the tumor. Weight loss and fatigue may be manifestations of cancer-consuming symptoms. These symptoms usually appear in the late stage of bladder cancer, indicating that the disease may have progressed. If these symptoms occur, you should immediately see a doctor for a comprehensive examination and treatment.

The symptoms of bladder cancer vary. Early symptoms may not be obvious, but hematuria is the most typical signal. Frequent urination, urgency, and pain during urination may also indicate the presence of bladder cancer. Other symptoms such as lower abdominal pain, weight loss, and fatigue may appear in the late stages. Early detection and treatment are the key to improving prognosis. It is recommended to seek medical attention for detailed examinations in a timely manner when the above symptoms occur. Urinalysis, cystoscopy, and imaging examinations can be used to confirm the diagnosis and develop an individualized treatment plan.
