How can we detect bladder cancer in the early stage? Pay attention to these causes of bladder cancer

When it comes to bladder cancer, many people may think that this disease is a rare disease, and they may think that it is not as malignant as lung cancer, stomach cancer, liver cancer and other malignant tumors. However, in fact, bladder cancer is the most common malignant tumor of the urinary system, and it has been on the rise in recent years. Since bladder cancer lacks specific early screening indicators, it is usually diagnosed only when patients have macroscopic hematuria, so the probability of early detection and early diagnosis of bladder cancer is low.

What are the characteristics of bladder cancer? Why do leaders often not get as satisfactory treatment results as ordinary people after contracting bladder cancer? Today, let us take a closer look at bladder cancer.

The main causes of bladder cancer are

Bladder cancer is more common in men, and the reasons are not fully understood, but the two major risk factors are smoking and long-term exposure to industrial chemical products. Smoking is the most certain causative factor for bladder cancer, with about 30%-50% of bladder cancers caused by smoking. Foreign data have confirmed that among various occupational groups, business people and administrative personnel are the number one high-risk group for bladder cancer because they have more opportunities to socialize with tobacco.

In addition, the risk factors of bladder cancer are closely related to daily living habits. It is generally believed that long-term use of traditional Chinese medicine containing aristolochic acid, long-term drinking of water with high hardness, long-term drinking of soda water, long-term intake of coffee and beverages rich in saccharin, long-term hair dyeing, long-term contact with decoration materials, large intake of high-fat food, long-term drinking, excessive intake of bean products, long-term intake of red meat and other ten factors are not ruled out as being closely related to the risk of bladder cancer. At present, the only factor confirmed to effectively prevent the occurrence of bladder cancer is to drink more boiled water every day (the local water hardness cannot be high).

70% of bladder cancers are detected early?

Bladder cancer treatment is mainly surgical. Clinically, about 70% of bladder cancer patients are diagnosed in the early stages. Endoscopic examination can directly see the size and depth of the tumor, which is not only conducive to taking out tissue biopsies, but also to resection through minimally invasive surgery. Usually, as long as the tumor is completely removed, bladder cancer can be cured.

About 30% of patients have deep tumors, so they need to remove the bladder to eradicate the lesions. Fortunately, many large tumor centers can reconstruct a new bladder at the original location after cystectomy, and the operation will not have much impact on the patient's life.

Data show that 70% to 80% of patients with early-stage bladder cancer can be cured after surgery, of which 20% to 30% may relapse, but they can still be cured as long as they are diagnosed and treated early. A small number of patients in the advanced stage can be treated with a combination of surgery and chemotherapy, but the treatment effect is far worse than that of early-stage patients, with a 5-year survival rate of about 50%.
