Is urinary pain a symptom of bladder cancer? To prevent bladder cancer, pay attention to a healthy diet

People over 50 are more likely to develop bladder cancer, and the incidence rate increases with age. To prevent bladder cancer, you can pay more attention to the following aspects:

What are the early symptoms of bladder cancer?

1. Frequent urination and urgency

If cancer cells invade the trigone of the bladder, irritation of the bladder may occur earlier, and if urination pain occurs, it is no longer in the early stage. If urination pain suddenly occurs for unknown reasons, it is a symptom of early bladder cancer.

2. Bladder irritation symptoms

The infiltration of the tumor itself, ulceration, necrosis, infection and blood clots of cancerous tissue can all become stimuli that cause the bladder muscles to contract and produce the urge to urinate; frequent urination (8%), urgency (8%), pain when urinating (5%) and persistent feeling of urinating, persistent distension and pain in the lower back, and urinary incontinence occur when the tumor invades the sphincter.

3. Symptoms of upper urinary tract obstruction

When the tumor invades the ureteral orifice, it causes the renal pelvis and ureteral orifice to expand and accumulate water, or even become infected, causing varying degrees of backache, back pain, fever, etc. If both sides of the ureteral orifice are invaded, symptoms of acute renal failure may occur.

4. Lower abdominal mass

About 3% of patients have this as the first symptom of bladder cancer, most of which are adenocarcinomas at the top of the bladder or solid bladder cancers with high malignancy in other parts. Rectal (or vaginal) digital examination or dissection of uneven masses can be used to understand the scope and depth of tumor infiltration into the bladder wall, which is helpful for tumor staging estimation.

To prevent bladder cancer, you can pay more attention to the following aspects:

1. You should stick to a scientific diet and eat more fresh vegetables and fruits. Try to eat less meat, because meat can produce substances similar to aniline and benzidine during metabolism in the body. A survey found that workers who are exposed to chemical raw materials such as aniline and benzidine are more likely to suffer from bladder cancer.

2. People who have the habit of smoking should quit smoking as soon as possible. Studies have shown that people who smoke a lot have higher concentrations of carcinogens in their urine.

3. Because the amount of water you drink directly affects the concentration of urine in the bladder, it has an important impact on the occurrence of bladder cancer. People who drink less water will inevitably have less urine in their bladders, and after carcinogens are excreted from the kidneys to the bladder, the concentration in the urine will be correspondingly higher. These high concentrations of carcinogens will cause strong irritation to the bladder mucosa. At the same time, for those who drink less water, the interval between urinations will inevitably be prolonged, which creates favorable conditions for the reproduction of bacteria in the bladder. Most people who often suffer from cystitis are those who do not like to drink water at ordinary times. The increase in the concentration of bacteria in urine can not only cause cystitis, but also have adverse irritation to the bladder mucosa. Over time, under the dual stimulation of bacteria and carcinogens, the bladder mucosa can gradually develop from inflammation and erosion to cancer. Therefore, you should drink more water in your daily life.
