Symptoms of Bladder Cancer

Bladder cancer has frequently appeared in life in recent years. There is no specific factor for the occurrence of cystitis, but it is very likely related to the patient's lifestyle habits. For many people, they may not know what the symptoms of bladder cancer are. In fact, if we know more about the disease, we can better identify whether the disease is in us.

The symptoms of bladder cancer are relatively obvious, including bladder pain, urgency and frequency of urination, and other abnormal conditions. Because these conditions are very similar to other urinary system diseases, suspected patients should go to a regular hospital for examination and treatment as soon as possible.

The cause is not yet fully understood, but it is associated with the following factors:

① Environment and occupation: It has been confirmed that beta-naphthylamine, benzidine, 4-aminobisphenyl, etc. are bladder cancer carcinogens. They are intermediate products in the manufacture of dyes or antioxidants in the rubber and plastics industries. Long-term exposure to these substances is prone to bladder cancer.

②Other abnormalities in tryptophan and niacin metabolism may be the cause of bladder cancer, but other chronic diseases also have such abnormalities. Schistosoma haematobium, leukoplakia, glandular cystitis, urinary stones, urinary retention, etc. that parasitize the bladder may also be causes of bladder cancer.

Pathology is related to the tumor's tissue type, degree of cell differentiation, growth pattern and infiltration depth, among which cell differentiation and infiltration depth are the most important. The tumors are most commonly distributed in the lateral and posterior walls of the bladder, followed by the triangular area and the top, and can occur in multiple centers. Bladder tumors may be accompanied by renal pelvis, ureter, and urethra tumors successively or simultaneously.

The spread of bladder tumors mainly infiltrates deeply into the extra-bladder tissues. Lymphatic metastasis is common. In patients with infiltration of the superficial muscle layer, about 50% of the lymphatic vessels contain control cells, while in patients with infiltration of the deep muscle layer, almost all of the lymphatic vessels contain cancer cells. When bladder cancer infiltrates into the surrounding tissues of the bladder, most of them have already metastasized to distant lymph nodes. Hematogenous metastasis usually occurs in the late stage, mainly to the liver, lungs, bones, skin and ribs, etc. Tumor cells with poor differentiation are prone to infiltration and metastasis.

1. Symptoms:

1. Intermittent painless macroscopic hematuria or microscopic hematuria;

2. Bladder irritation symptoms such as frequent urination, urgency, and pain during urination. If the tumor is large or occurs at the bladder neck, it can cause urine flow obstruction, difficulty urinating, and even urine retention.

3. It causes hydronephrosis, resulting in low back pain, back pain, fever, etc.

2. Diagnostic criteria:

The diagnosis can be made based on clinical manifestations and examination.

The above is an introduction to the symptoms of bladder cancer. I hope that after reading it, you will have a deeper understanding of bladder cancer. For patients with bladder cancer, they need to pay attention to various habits in life. If the living habits are not corrected, the condition will definitely worsen, which is not good.
