A few days ago, a well-known actor Yang Qun , who has starred in many film and television works such as "Qin Xianglian", "Several Sunset Red", " New Bao Qingtian ", died of bladder cancer at the age of 88. His departure made many viewers who loved him sad and regretful.
According to the 2020 Global Cancer Statistics Report, bladder cancer, the 10th most common malignant tumor disease in the world, has 573,000 new cases and 213,000 deaths every year. Especially in recent years, bladder cancer has shown a high incidence in my country, ranking first among male malignant tumors. However, because the early symptoms of bladder cancer are not obvious and the tumor is "concealed and quiet", it is often easy to lead to misdiagnosis and missed diagnosis. So, how should people prevent, detect and treat bladder cancer early?
has a higher incidence rate in men than in women
is prone to misdiagnosis and misdiagnosis
"Broadly speaking, malignant tumors originating from bladder are called bladder cancer, among which urothelial cancer is the most common pathological type. This disease is more common in people over 50 years old and has a higher incidence rate in men than in women." Li Qiang, deputy director of the Department of Abdominal Surgery at Shaanxi Provincial Cancer Hospital, introduced.
In response to the high rate of misdiagnosis and misdiagnosis of bladder cancer, Li Qiang said that bladder cancer presents intermittent and painless hematuria in the early stages, but often does not feel pain. There are also a few patients who have non-numb-eye hematuria, and hematuria also occurs intermittently. In this case, patients often think it is bladder inflammation. In addition, intermittent hematuria can be stopped or relieved without treatment, which can easily cause the patient to have an illusion that the disease is "cured" or "better", thereby causing the disease to be misdiagnosed and misdiagnosed. In addition, the B-ultrasound examination performed by patients with bladder cancer is sometimes difficult to detect some early cancers, and some patients have cystoscopy. However, due to the special morphology of some bladder tumors, , which can also cause missed diagnosis.
Smoking will increase the incidence of bladder cancer by nearly 4 times
The incidence of bladder cancer is a process of mixed and multi-step formation, with both internal genetic factors and external environmental factors. The two most obvious high-risk pathogenic factors are smoking and occupational exposure to .
Li Qiang pointed out that smoking is an internationally recognized risk factor for bladder cancer. The aromatic amine and polycyclic aromatic hydrocarbons contained in the smoke after cigarettes are carcinogens. Nearly 50% of bladder cancer patients are related to smoking, and smoking will increase the incidence of bladder cancer by nearly 4 times. There are also people who have been engaged in occupations such as dyes, leather, rubber, plastics, and paint for a long time, which will significantly increase the risk of bladder cancer.
In addition to smoking and occupational exposure to bladder cancer, bladder stones , bladder diverticulum , chronic bladder infection, as well as genetic factors and long-term stimulation of foreign bodies, will increase the risk of bladder cancer.
hematuria, frequent urination , urination pain, back pain
These signals should be alert to the fact that
early bladder cancer has no obvious symptoms, but as the tumor grows and develops, urinary tract symptoms such as hematuria, frequent urination, and frequent urinary tracts appear, and often occur. Often, patients come to seek medical treatment at this time, which is easy to delay the early detection and early treatment of bladder cancer.
"The hematuria symptoms of bladder cancer have their own characteristics, which are painless and intermittent hematuria . Once hematuria has the above characteristics, the patient needs to pay attention to it, seek medical treatment and check it in time to clarify the cause. However, hematuria is not the only signal of bladder cancer. Some bladder cancer patients sometimes have some urinary irritation symptoms such as frequent urination, urgency, and pain." Li Qiang pointed out that there is another symptom that needs to be vigilant, that is back pain. Because the kidneys discharge urine into the bladder through the ureter, if the bladder tumor grows in the opening of the ureter, blocking the opening of the ureter, causing urine in the kidney to be unable to discharge into the bladder, resulting in the kidney hydrops, and subsequent symptoms of back pain.
Currently, bladder cancer is mainly treated with surgery. Because of the risk of recurrence, patients need regular examinations after the operation.
Remember five things
Stay away from bladder cancer
Although bladder cancer is "hidden and quiet", as long as people pay more attention in their daily lives, they can still stay away from the invasion of bladder cancer to the greatest extent.
Li Qiang suggested that you should keep in mind the "five things" in life, that is, don't hold your urine first. If you hold urine for a long time, it may cause harmful substances in the urine to stay in the bladder for a long time, increasing the risk of cancer.
Secondly, drink more water. If you drink more water, you will urinate more times, so that the time for harmful substances to stay in the bladder will be reduced.
Third, it is necessary to reduce contact with dyes and hair dyes, because long-term exposure to aromatic amine chemicals can increase the risk of bladder cancer.
The fourth is not to smoke. Smoking is the most certain risk factor for bladder cancer.
Finally, do not ignore chronic obstruction caused by prostate hyperplasia, as well as urinary retention , bladder stones and other diseases.
Li Qiang reminds that having a healthy lifestyle, a reasonable diet, and a good mentality also has a positive effect on preventing bladder cancer. China Business News reporter Wu Jie
