Frequent urination and urgency Tumor cells invade the bladder triangle, it will stimulate the bladder, and it can also detect the early symptoms of bladder cancer in time. If the symptom of frequent and urgent urination appears suddenly, it indicates that it is the early stage of bladder cancer, and it is relatively easy to be treated at this time, and sudden urinary pain is also a symptom of bladder cancer. Pain When the cancer invades the bladder more widely and the invasion is deeper, urinary pain will occur, and the pain will be aggravated when the bladder is holding up and contracting. If the cancer invades the bladder neck and leads to urethral obstruction, it may induce urinary retention. If the cancer invades the urethral orifice, it may lead to upstream infection or even pyelonephritis. If the condition is more serious, it may turn into uremia, and malignant disease will appear in the advanced stage of bladder cancer. Hematuria Bladder cancer in early stage has almost no feeling, only the phenomenon of hematuria that can be observed by naked eyes. This symptom is the “red alert” of bladder cancer, which is common to almost every patient with bladder cancer, experts say, this abnormal symptom of bladder cancer should be diagnosed in time to find out the cause of bladder cancer and treat the symptom in time. Frequent urination and urgency may be the precursor of bladder cancer Although bladder cancer is scary, it is not incurable, and the most important thing is to treat it in time and cooperate with doctors actively. If early symptoms of bladder cancer are found but not treated in time, the best time for treatment will be lost. Please grasp the best treatment period. Urinary tract irritation symptom This late bladder cancer symptom can appear or be dominated by this symptom when the tumor occurs in the bladder triangle or when it is combined with infection. Bladder irritation symptoms also reveal the possibility of carcinoma in situ of the bladder, so patients with bladder irritation signs lacking a sufficient basis for infection should be thoroughly examined as soon as possible to rule out bladder cancer. Others: If the tumor infiltrates into the ureteral orifice or grows in the ureteral orifice, it can cause ureteral dilatation of advanced bladder cancer symptoms, and then form hydronephrosis and increase the size of kidneys. When bladder cancer develops lung, liver and bone metastasis, corresponding symptoms appear, such as cough, shortness of breath, abnormal liver function, pain in liver area, bone pain in a certain place.
