Bladder cancer is one of the most common malignant tumors in the urinary system. Currently, the exact cause of bladder cancer is not clear. In terms of prevention, it is generally necessary to drink more water, urinate more frequently, try not to smoke, and reduce exposure to chemical irritants, such as paint, chemical substances, etc. Additionally, an annual physical examination is recommended to enable early detection and early treatment.

What is the best medicine for bladder cancer infusion?

Bladder perfusion chemotherapy involves infusing chemotherapy drugs directly into the bladder through a catheter to control tumor growth and reduce the recurrence rate after surgery. Generally, the drugs with significant effects on bladder perfusion fall into three categories. The first category is the anthracyclines, including doxorubicin, epirubicin, and pirarubicin. The second category includes platinum-based drugs such as cisplatin, carboplatin, and oxaliplatin. The third category is vinorelbine. According to current big data research, vinorelbine bladder perfusion tends to have a lower recurrence rate. Without postoperative bladder perfusion chemotherapy, 60%-70% of patients will eventually experience recurrence. With bladder perfusion chemotherapy, the recurrence rate can be reduced to 20%-30%.

The difference between bladder tumor and bladder cancer is that a bladder tumor may be benign or malignant, whereas bladder cancer specifically refers to a malignant tumor.

The difference between bladder tumors and bladder cancer generally lies in whether the growth inside the bladder is benign or malignant. Normally, nothing should grow inside the bladder. However, if a growth does appear, it can be referred to as a bladder tumor if it is benign, or bladder cancer if it is malignant. Bladder tumors are typically round with clear boundaries, which can be observed through ultrasound or cystoscopy. On the other hand, if the growth in the bladder resembles seaweed or cauliflower, with unclear boundaries, erosion, bleeding, or other symptoms, it can be referred to as bladder cancer. Generally, the primary treatment for such cases is surgical removal.

Early symptoms of bladder cancer

Hematuria is the most common and earliest symptom of bladder cancer, with 85% of patients experiencing intermittent gross hematuria which can decrease or stop on its own, often giving patients a false impression of improvement or cure, thus delaying treatment. Sometimes, hematuria is also found under a microscope, and the amount of bleeding is not necessarily consistent with the size, number, or malignancy of the tumor. The hematuria from bladder tumors can initially be mild, and other symptoms such as frequent urination, urgency, and painful urination may also occur; these are all manifestations of bladder tumors.

Does bladder cancer require the removal of the bladder?

Whether or not to remove the entire bladder in cases of bladder cancer depends on whether the tumor has invaded the base layer and whether there is distant metastasis. For non-muscle invasive bladder cancer, where the muscle layer is not invaded and there is no distant metastasis, typically found in stage 0 and stage 1 bladder cancer patients, there is no need for complete removal of the bladder. The standard treatment in such cases generally involves transurethral resection of the bladder tumor. If the tumor has invaded the base layer but there is no distant metastasis, termed muscle-invasive bladder cancer, patients in this category require radical cystectomy, which involves the removal of the entire bladder. If there is distant metastasis, termed metastatic bladder cancer, surgical treatment is not pursued; instead, palliative chemotherapy is the primary approach.

The most common clinical manifestations of bladder cancer

The most common clinical manifestations of bladder cancer include: one initial clinical presentation is hematuria, which typically appears as painless, intermittent gross hematuria, sometimes it can also manifest as microscopic hematuria. The hematuria may occur only once or last from one day to several days, and it can subside or stop on its own. The color of the hematuria can be light red, possibly dark brown, generally dark red. The amount of bleeding and the duration of the hematuria are not necessarily proportional to the malignancy degree, size, scope, and number of the tumor. Additionally, bladder cancer patients can experience symptoms of bladder irritation, such as frequent urination, urgent urination, painful urination, and difficulties in urination, etc.
