Early symptoms of bladder cancer: 1. Hematuria: The initial clinical manifestation of more than 90% of patients with bladder cancer is hematuria, which is usually painless, intermittent, or microscopic hematuria. If it is painful or itchy, it may be a benign disease, but if it is painless hematuria, then it is likely to be a malignant disease.
2.Urinary frequency, urinary urgency and pain: Tumor cells invading the bladder triangle will stimulate the bladder, and the early symptoms of bladder cancer can be detected in time. If the symptom of urinary frequency and urgency suddenly appears, it means that it is the early stage of bladder cancer, which is relatively easy to treat at this time, and sudden painful urination is also a symptom of bladder cancer.
3.Other: If the cancer invades the bladder neck and leads to urethral obstruction, it may induce urinary retention. If the cancer invades the ureteral orifice, it will lead to upstream infection or even hydronephrosis. If the disease is more serious, it may turn into uremia, and in advanced stage of bladder cancer, cachexia will appear.
When these abnormal symptoms appear, you should come to the hospital for diagnosis in time to find out the cause and treatment.
