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.

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.

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.

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.

How is bladder cancer caused?

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.

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.
