What are the early symptoms of bladder cancer? If you have bladder cancer, the most common symptom is hematuria. In fact, after hematuria appears, people will not feel pain. Sometimes if people don't pay attention, they will easily ignore this disease, so it is important to understand the early symptoms of the disease. So, what are the early symptoms of bladder cancer?

The early symptoms of bladder cancer are as follows:

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 occurs sooner or later in 100% of cases 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 (8%), urgency (8%), pain when urinating (5%) and persistent feeling of urinating, persistent distension and pain in the waist, 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 urine 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.

After reading the above introduction, you should understand the early symptoms of bladder cancer. If you have bladder cancer, you may also have a concurrent infection, which will cause urinary tract irritation and other conditions, which can easily lead to worsening of the disease, making the treatment of the disease more difficult.
