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.

Diet for Bladder Cancer Patients

From the perspective of Western medicine, the diet for bladder cancer patients involves drinking plenty of water, avoiding spicy foods, and abstaining from alcohol and tobacco. Patients should also ensure they get enough vitamins by consuming fresh fruits and vegetables. Additionally, it is important to consume adequate nutrition including eggs, meat, and fish, and patients should not hold in urine. However, from the perspective of Chinese medicine, bladder cancer patients should avoid foods that induce excessive internal heat, such as lamb and seafood, and should also avoid cold or chilled foods.

Treatment of bladder cancer

For the treatment of bladder cancer, it is necessary first to confirm the diagnosis of bladder cancer through routine urine tests, ultrasonographic examination of the urinary system, cystoscopy, and imaging studies of the urinary system. It is important to determine the location, area, and malignancy of the bladder tumor. For early-stage superficial bladder tumors or tumors on the bladder wall with fewer numbers, minimally invasive surgery can be performed, followed by bladder perfusion to prevent recurrence of the bladder tumor. In the second scenario, if the bladder tumor is multiple and larger, and has a higher degree of malignancy in the bladder trigone area, then a radical cystectomy is required. Radical cystectomy involves the removal of the bladder along with the prostate in males or the uterus in females, followed by the creation of a urinary diversion, typically through these two treatment methods.

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%.

Is a bladder tumor the same as bladder cancer?

Not all bladder tumors are bladder cancer, as we all know, all tumors can be benign or malignant. Of course, bladder tumors can also be benign or malignant. Only malignant bladder tumors are considered bladder cancer. If some bladder tumors are benign, they cannot be called bladder cancer. Therefore, no matter how a bladder tumor is diagnosed, whether it is benign or malignant, it should be treated as soon as possible.

Is the bladder cancer embryonic antigen high?

Carcinoembryonic antigen (CEA) is significantly elevated, mainly seen in gastrointestinal tumors, especially in colorectal cancers such as colon and rectal cancers, where CEA elevation is more pronounced. It can also be notably higher in patients with lung adenocarcinoma, and bladder cancer might show an increase in CEA as well. However, the increase in CEA is not necessarily consistent, and its diagnostic value for bladder cancer is limited due to low specificity and sensitivity, making it not very instructive. The definitive diagnosis of bladder cancer primarily involves cystoscopy and taking a biopsy to confirm the presence of cancer.
