What harm does bladder cancer do to the body

Bladder cancer is a disease that is prone to occur in the middle-aged and elderly. It has a very serious impact on the urinary system. Therefore, patients must face up to the impact of this disease and actively carry out corresponding treatment in the clinic. If it is not well controlled, it may lead to further expansion of cancer cells, thereby having a bad impact on other functions of the body. The following is a detailed introduction to the harm that bladder cancer can bring to the body.

1. Hematuria is the most common first symptom of bladder cancer. 85% of patients may experience recurrent painless intermittent macroscopic hematuria. The amount of bleeding may be more or less, and in severe cases, there may be blood clots. Hematuria will occur sooner or later in 100% of the patients during the course of bladder cancer.

2. Symptoms of bladder irritation: Infiltration of the tumor itself, ulceration, necrosis, infection and blood clots of cancerous tissue can all become stimuli that cause the bladder muscles to contract and produce the urge to urinate; frequent urination, urgency, pain and persistent feeling of urination, persistent distension and pain in the lower back, and urinary incontinence when the tumor invades the sphincter.

3. Difficulty in urination. About 7% of bladder cancer patients experience difficulty in urination, and even urinary retention, due to the shedding of cancer tissue or the tumor itself and blood clots blocking the internal opening of the bladder.

4. Symptoms of upper urinary tract obstruction When cancer invades the ureteral orifice, it causes dilation and accumulation of water in the renal pelvis and ureteral orifice, and even infection, which can cause varying degrees of backache, back pain, fever, etc. If both sides of the ureteral orifice are invaded, symptoms of acute renal failure may occur.

5. About 3% of bladder cancer patients present with a lower abdominal mass as the first symptom, most of which are adenocarcinomas at the top of the bladder or highly malignant solid bladder cancers in other parts of the body.

It should be noted that bladder cancer can also be complicated by infection. Generally speaking, if there is a concurrent infection, the patient will also experience symptoms such as urinary tract irritation. However, if it is in the late stage of bladder cancer, the patient's chance of metastasis is very high, and the most common route of metastasis is direct invasive metastasis.
