Men who smoke know that smoking is harmful and healthy, but what harm will be harmful, and male friends do not know themselves.Here we point out that smoking can lead to the occurrence of bladder cancer, so smoking men should pay attention to it.So why does smoking lead to the occurrence of bladder cancer?Let's take a look here.
Causes of cigarettes lead to cuscomat
In developed countries, the bladder cancer caused by smoking has accounted for 50%of the total number of bladder cancer. It has become the most important pathogenic factor for bladder cancer.Tobacco contains a large amount of toxic substances, where the relationship is closely related to bladder cancer is aromatic amine and acrylic.
A large number of studies have shown that the risk of smokers suffering from bladder cancer is four times that of non -smokers, and as the number of smokers increases and the age of smoke is extended, the risk of bladder cancer has also increased accordingly.
The research report published in the new issue of "Magazine of the International Cancer" states that children who have long -term passive smoking in smoking environment have increased significantly in danger of bladder cancer when they grow up.The results of the study also show that every 5 years of smoking starts, the probability of bladder cancer is reduced by 19%.In other words, the younger the age of being stimulated by cigarettes, the higher the probability of bladder cancer.
Causes of bladder cancer
Exogenous carcinogenic substances
Workers engaged in aniline dyes have a particularly high incidence of bladder cancer, and the incidence rate increases with the age of work.The concentration of phenols in the urine is 200 times higher than the normal value. If the diversion of the urine is discharged without the bladder, the bladder tissue does not cause cancer.In addition, the carcinogenic substances in smoking and daily life are also considered one of the causes of bladder cancer.
Endogenous carcinogenic substances
Slicerine and tobaccoic acid metabolic abnormalities. The middle product is adjacent to hydroxylophenol, which can directly affect the synthesis of RNA and DNA of the cells. It has carcinogenic performance and increased the number of pigmentation products in urine in patients with bladder tumors.
Other carcinogenic factors
After suffering from Egyptian hemorrhoids, the stimulation of blood suction eggs in the bladder wall is prone to bladder tumors.my country ’s hemophilia is caused by Japanese blood and insect disease, which does not cause this lesion.Bladder mucosal leukemia, glandular cystitis, stones, long -term urine retention, and some virus infections are also one of the causes of bladder tumors.
Bladder cancer can cause complications
1. Difficulty in urination: For a small number of patients due to large tumors, or tumors occur on the neck of the bladder, or the formation of blood clots, which can cause urinary flow obstruction, urination difficulty, or even urinary retention.
2. Symptoms of bladder stimulation: Symptoms of urinary tract stimulus have less early bladder tumors.If the bladder tumor is accompanied by infection at the same time, or the tumor occurs in the bladder triangle area, the symptoms of urinary tract stimulation can appear earlier.In addition, the symptoms of bladder irritation such as frequent urination, urgency, and urgency may indicate the possibility of bladder in situ cancer.Therefore, patients with lack of infection basis should adopt positive and comprehensive examination measures to ensure early diagnosis.
3. Symptoms of upper urinary tract: When cancer infiltrates the ureter mouth, it causes pelvis and ureter to expand accumulated water, and even infection, causing symptoms such as backache, low back pain, and fever.If the bilateral ureter mouth is invaded, the symptoms of acute renal failure can occur.(Reference website: Huaxia Health Network)
