Firstly, it is not possible to determine the presence of bladder cancer in this way. If, after urinating, there is blood-tinged fluid when wiping the urinary opening with tissue, this may be considered hematuria. There are many causes of hematuria, such as urinary tract infections, or swelling, congestion, and erosion at the urinary opening, as well as kidney stones, all of which can lead to blood in the urine.

Of course, tumors in the urinary system can also cause blood in the urine, but tumor-induced hematuria is often painless, and the color of the blood tends to be concentrated, making the urine appear red or like washed meat water. In such cases, it is important to promptly visit a hospital for routine urinalysis, ultrasonography, and even CT scans or cystoscopy to determine if it is bladder cancer.

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.

What are the symptoms of late-stage bladder cancer?

The symptoms of late-stage bladder cancer include: 1. Difficulty urinating. Due to the large size of the tumor, its location at the neck of the bladder, or the formation of blood clots, there can be blockage of urine flow, difficulty urinating, and even urinary retention. 2. Bladder irritation symptoms. Early-stage bladder often shows fewer urinary irritation symptoms, but when the tumor occurs in the trigone area of the bladder, urinary irritation symptoms may appear earlier. There are also symptoms of upper urinary tract obstruction, such as when the cancer invades the ureteral orifice, causing dilation and accumulation of fluid in the renal pelvis and ureter, and even infections leading to backache, waist pain, fever, etc. Additionally, there are general symptoms, including nausea, reduced appetite, fever, weight loss, anemia, cachexia, and more.

What are the symptoms of bladder cancer?

Bladder cancer's most common symptom is a consistent presence of painless gross hematuria. Some patients also exhibit frequent urination, urgency, and pain during urination as initial signs of bladder irritation. In advanced local stages, palpable pelvic tumors can be detected in patients, with symptoms such as urinary retention, lower abdominal pain, and inability to urinate. In the late stages of bladder cancer, patients may experience weight loss, back and flank pain, and signs of renal failure among other clinical manifestations.

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.
