Hematuria is the most common clinical symptom of bladder tumor. No matter male or female, middle-aged or elderly people need to be highly alert to the possibility of tumor once hematuria occurs. In real life, some people have concerns about urine bleeding, feel embarrassed and afraid of gossip, and dare not go to the doctor, thus delaying the condition themselves. Some people do not go for further examination because they think they are fine after their urine bleeding has stopped. In fact, some tumors are intermittent bleeding, the original bleeding point is clotted and will not bleed for a period of time, but the tumor is still there and it continues to grow and further endanger human health. Therefore, as long as there has been hematuria, or even urine test red cells (medically known as microscopic hematuria) are found during physical examination, you need to go to hospital for further examination. Mr. Wang, 65 years old this year, for a long time urine has been very red, sometimes although a little lighter, like washing meat water, sometimes deep like soy sauce color. So his family took him to the hospital, and after ultrasound examination, it was found that there was a 4 cm diameter mass in Mr. Wang’s bladder, then a cystoscopy was done and a small piece of tissue was removed for pathological tests, and the pathological results confirmed that it was a malignant bladder tumor, i.e. bladder cancer, and that it had invaded the muscle layer. Mr. Wang recalled that he had similar urine bleeding six months ago, but the color was not as dark as it is now, so he was embarrassed to tell his family about it and did not go to the hospital for examination because he felt that urine bleeding was a secret. This time, the doctor gave Mr. Wang a full body checkup and found no signs of tumor metastasis, but still had to remove the whole bladder. In fact, bladder tumor is not terrible, currently it can be eradicated through surgery, and after eradication patients can live as normal. Of course, as with all tumors, early detection and early treatment is the key. For early bladder tumors, patients have a longer survival period after surgery. If the tumor is small and superficially located in the bladder, the bladder usually does not need to be removed, and the tumor can be removed through minimally invasive surgery such as plasma and laser, which is also less painful and quicker to recover. In daily life, it is important to strengthen the measures to prevent bladder cancer. Smoking is an important precipitating factor of bladder cancer, so it is necessary to quit smoking. In addition, it is also necessary to minimize exposure to toxic and chemical substances, such as substances containing aromatic amines, hair dyes, arsenic and radiation.
