Real case
Mr. Du is a decoration Company Painter, the body has always been good. Nearly two months of urine, he occasionally found that the urine color is dark brown, he thought it was less water, ' lit ' the reason, also did not pay attention to.
However, this week, Mr. Du's urine color is like the washing of meat, even the frequency of urine, urine, urine pain symptoms, after medical examination found that he suffered Bladder cancer.
Mr. Du is very surprised, his normal body also nothing strange, how to relate to cancer. It turns out that Mr. Du is a more than 10-year-old smoker, and has been working in paint for seven or eight years.
The doctor told him that Mr Du's ' culprit ' for bladder cancer was long-term exposure to paint and smoking.
Inducement: Smoking is the main culprit The high incidence of bladder cancer was 50-70 years, and the male prevalence was much higher than that of females, about 4:1.
Smoking is the most common cause of cancer, and about 1/3 of bladder cancer is associated with smoking.
The greater the smoking volume, the longer the smoking history, the higher the concentration of carcinogenic substances in the urine, the greater the risk of bladder cancer.
Second, long-term exposure to certain chemical raw materials, such as dye, paint, printing and other occupations, the risk of bladder cancer is much higher than the average person.
In addition, chronic bladder infection and foreign body of long-term stimulation, such as bladder stones, bladder leukoplakia, etc. will increase the risk of bladder cancer.
Symptom: Painless Hematuria Hematuria refers to the abnormal increase of RBC in urine, which is a common symptom of urinary system.
Most of the causes of hematuria are related to calculus, tuberculosis, inflammation, tumor or trauma. If it is a stone, inflammation or trauma caused by hematuria, usually accompanied by frequent urination, urinary urgency, urine pain symptoms;
If painless hematuria is more frightening, it is often a dangerous sign of urinary tract tumors. According to statistics, painless naked eye hematuria patients with bladder cancer probability of 1/3, high in the urinary tract tumor first.
Not all patients with hematuria will be active in the first time, which has a great relationship with the characteristics of urinary bladder cancer. First of all, bladder cancer hematuria is painless, often difficult to attract enough attention;
Secondly, the hematuria of bladder cancer is intermittent, that is, hematuria will stop or reduce itself, two times of hematuria can be separated for several months or longer.
Some patients are in the presence of frequent urination, urine, pain and other accompanying symptoms come to the hospital, and often accompanied by infection or tumor necrosis, ulcers, doctors collect medical history when the patient recalls the previous one or two times hematuria experience. There are also some patients, the bladder neck tumor obstruction due to bladder outlet, resulting in dysuria and even urine retention; And some patients will be due to the gradual increase in bladder tumor, can be in the lower abdomen to touch the prominent masses.
If these patients can get to the hospital early, the situation is far from so bad.
Check: Urine routine and B-ultrasound, is a routine inspection means High-risk groups recommend a urinary system B-ultrasound and urine routine examination, early detection of bladder mass and the naked eye can not see the hematuria.
This examination is often used as a preliminary screening for Hematuria. In addition, CT and MRI can observe the tumor size, location, and the scope of tumor invasion.
When imaging is shown to have tumors or have no imaging evidence but highly suspected tumor patients, the doctor will consider the diagnosis of cystoscopy.
Treatment: Surgical resection
Surgical resection is the main method for the treatment of bladder cancer, for metastatic bladder cancer or for bladder cancer patients who are not suitable for operation, it is possible to adopt systemic radiotherapy and chemotherapy to improve survival rate. Reminder: Bladder cancer recurrence rate is quite high, in more than 50%, some patients will also occur lymphatic metastasis.
It is especially important to review the cystoscopy at least once every 3 months after the operation of bladder cancer. Urine is like a meat-washing water | Beware of bladder cancer
