What are the symptoms of bladder cancer?

The precursors of bladder cancer include hematuria, frequent urination, urgency, and difficulty urinating. If unexplained hematuria occurs, you should see a doctor as soon as possible for timely examination and diagnosis.

Hematuria is the most common early sign of bladder cancer. It may appear as red urine visible to the naked eye or may just be occult blood found under a microscope and is usually painless. Urinary tract irritation symptoms such as frequent urination, urgency, and burning during urination may also occur, especially if the tumor is close to the trigone of the bladder. It may also be accompanied by difficulty or interruption in urination, and even be mistaken for a prostate problem in men. Advanced bladder cancer may cause bone pain, weight loss, lower back pain, or chronic fatigue, indicating that the cancer has metastasized.

Early screening for bladder cancer can significantly increase the cure rate, especially when the above symptoms are found. Doctors usually help confirm the diagnosis through urine tests, cystoscopy, and imaging (such as CT, MRI). At the same time, maintaining good living habits, such as quitting smoking and drinking more water, can reduce the risk of disease. If there are high-risk factors such as family history or occupational exposure, you should have regular physical examinations and keep in touch with your doctor to ensure your health.
