People with bladder cancer usually have bladder irritation symptoms

People with bladder cancer generally have bladder irritation symptoms, but only a few people have this symptom. So do you know what the symptoms of bladder cancer are? This is also a question that people ask a lot. The following authoritative experts will give you a detailed answer.

The main symptoms of bladder cancer include:

(1) Symptoms of late-stage tumors: When late-stage tumors invade the tissues and organs around the bladder or metastasize to the pelvic lymph nodes, they can cause corresponding symptoms such as bladder pain, urethro-vaginal fistula, and lower limb edema. When metastases occur to distant sites, symptoms such as impaired function of the metastatic organ, bone pain, and cachexia may also occur. These are also symptoms of bladder cancer.

(2) Symptoms of urinary obstruction: Large tumors, tumors at the bladder neck, and blood clots can cause difficulty in urination or even urinary retention. Tumor infiltration of the ureteral orifice can cause upper urinary tract obstruction, resulting in low back pain, hydronephrosis, and renal impairment, which are also symptoms of bladder cancer.

(3) Bladder irritation symptoms: frequent urination, urgent urination, and painful urination, accounting for about 10%, are related to widespread carcinoma in situ and invasive bladder cancer, especially when the lesion is located in the bladder trigone. Therefore, patients with long-term "cystitis" that cannot be cured should be alert to the possibility of bladder cancer, especially carcinoma in situ, which is a symptom of bladder cancer.

(4) When the tumor is large, vaginal or rectal bimanual palpation may be used to feel the mass, but this method is not accurate enough. In addition, bimanual palpation may not be able to examine all parts of the bladder, and the poorly relaxed abdominal wall is even more difficult to examine clearly. In recent years, with the advancement of imaging, this examination has been rarely used.

(5) Hematuria: Painless macroscopic hematuria is a symptom of bladder cancer, which may occur in more than 80% of patients, of which 17% have severe hematuria, but 15% may only have microscopic hematuria at the beginning. Hematuria is usually intermittent throughout the whole process, and may also present as initial hematuria or terminal hematuria. Some patients may excrete blood clots or necrotic tissue. The duration of hematuria and the amount of bleeding are related to the malignancy, stage, size, number, range, and morphology of the tumor, but they are not necessarily proportional. Carcinoma in situ often presents as microscopic hematuria, while hematuria in urachal carcinoma of the bladder may not be obvious. Bladder tumors of non-urothelial origin may not have hematuria if the lesions do not penetrate the bladder mucosa.

The above is the explanation given by experts on the symptoms of bladder cancer. Painless macroscopic hematuria may also be caused by this disease. Experts remind everyone that if you suffer from any disease in your daily life, you must not delay treatment. This is very dangerous. Some diseases will worsen or cause other diseases.
