The causes of bladder cancer are not very clear so far, and they are related to factors such as environment, genetics, and lifestyle habits. However, two major risk factors are quite clear: one is smoking, and the other is long-term exposure to aromatic amines, which are occupational factors that are significant risks for causing bladder cancer.

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.

Is bladder cancer contagious?

Bladder cancer is not contagious, so there is no need to worry about that. Bladder cancer occurs when there is a cancerous transformation of bladder tissue, leading to the formation of bladder tumors. If the tumors are malignant, they are generally termed bladder cancer. Causes of bladder cancer can include long-term exposure to certain carcinogens, such as occupations involving dyes, leather, or paintwork. Another carcinogenic factor is smoking, which is related to about one-third of bladder cancer cases. Chronic infection or prolonged irritation by foreign bodies can also increase the risk of bladder cancer, as seen in cases with bladder stones, bladder diverticula, or chronic cystitis.

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.

How is bladder cancer treated?

How is bladder cancer treated? Currently, the primary treatment option for bladder cancer is surgery, which can include procedures like transurethral tumor resection, bladder tumor resection, urethral tumor resection through the bladder, and cystectomy, among others. The specific surgical approach is selected based on factors such as the location and size of the bladder cancer. Besides surgical removal of the bladder, other treatment methods such as radiation therapy, chemotherapy, new technology treatments, and traditional Chinese medicine are also available as adjunct therapies. The formulation of a treatment plan should comprehensively consider factors such as the location, size, and stage of the bladder cancer.

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.
