A well-known actor died of cancer, which is very "quiet", be alert to these high-risk factors!

According to reports, on October 24, the well-known actor Yang Qun died of bladder cancer and has been struggling with the disease for more than a year, but his condition deteriorated, the cancer cells spread, and finally he was powerless
.

Bladder cancer, which originates from the bladder mucosa, is the most common cancer of
the urinary system.
One of the most common types of pathology is urothelial cell carcinoma, which accounts for more than
90% of bladder cancers.
In recent decades, the incidence and mortality of bladder cancer in China have shown an upward trend
.

What are the clinical manifestations of bladder cancer?

Currently, known risk factors for bladder cancer include aging, smoking, invisible hematuria, occupational exposure to aromatic amines (dyes, chemicals, rubber industry), arsenic-containing drinking water, history of bladder infection, and family history of
bladder cancer.

In addition, more than 90% of patients with bladder cancer have early clinical symptoms of hematuria, usually painless gross hematuria, and sometimes microscopic hematuria
.
A small number of patients have early bladder irritation and are characterized by frequency, urgency, dysuria, and dysuria
.

Symptom 1: intermittent, painless, gross hematuria
.
The patient's urine is as colored as
blood.
Because the surface of the tumor is very fragile, there are many new blood vessels, and as soon as the blood vessels are broken, the blood will flow into the bladder and be discharged with urine, so it is called hematuria
.
The whole process refers to a single urination from the beginning to the end, which is hematuria
.
Intermittent is because blood vessels are sometimes repaired and urine is normal
.

There is a condition of urine that cannot be seen red with the naked eye, but there are red blood cells under the microscope, and this kind of microscopic hematuria should also be paid attention
to.

Symptom 2: frequent urination, urgency
.
The two ureteral orifices and the inner orifice of the urethra are more sensitive to nerves, and if they are stimulated by the lesion, there are symptoms of
wanting to urinate.

Symptom 3: Low back pain
.
The urine received by the bladder is from the kidneys and ureters, if the tumor grows in the position of the ureteral opening, blocking the ureteral opening, the urine in the kidney can not come out, it will cause increased pressure in the kidney, hydronephrosis, accompanied by low back pain
.

Symptom 4: dysuria
.
In general, bladder cancer is painless, some patients have a very large tumor, the surface is broken, infection combined with inflammation, there will be a feeling
of painful urination.

How to stay away from bladder cancer?

1.
Do not hold urine
.
There is no direct evidence
of bladder cancer due to urine holding.
The function of the bladder is to store urine, and the mucosal layer has a certain barrier effect and does not absorb urine toxins
.
However, after the bladder is overfilled, the contraction force of the bladder muscularity becomes weaker, and the urine storage and urination functions of the bladder are affected
.

2.
Don't lack water
.
Drinking more water can prevent bladder cancer, because drinking more water will make more urine, and the concentration of carcinogens in the urine will not be too high
.
If you drink less water every day, there is less urine in the bladder and a higher concentration of carcinogens in the urine, which can cause irritation
to the bladder mucosa.
Therefore, to develop a good habit of drinking water every day, it is best to remind yourself to drink some water every half hour, do not drink water because of busy work and bury the risk
of cancer.

3.
Don't smoke
.
Studies have found that smoking can increase the risk of bladder cancer by 2~6 times
.
With the prolongation of smoking, the incidence of bladder cancer also increases significantly
.
The smoking rate is significantly higher among men than in women
.

4.
Do not dye your hair
frequently.
Chemical dyes may also cause bladder cancer, and frequent exposure to aromatic amines is a well-established risk factor for
bladder cancer.
Barbers and middle-aged and elderly people who often dye their hair may be at high risk of
bladder cancer.
Therefore, although hair coloring can bring people back to a young state visually, it is also necessary to consider health issues, moderate amounts, and try to avoid frequent hair
coloring.

5.
Don't ignore prostatic hyperplasia
.
Prostatic hyperplasia and urethral stricture and other diseases cause chronic urinary tract obstruction, long-term aggregation of tumorigenic substances in the bladder can easily cause bladder cancer, and local chronic long-term stimulation such as stones can cause bladder squamous cell carcinoma
.

What are the treatments for bladder cancer?

Due to the obvious early symptoms of bladder cancer, more than 80% of bladder cancers are in the early stage of diagnosis, which can generally be treated
by cystoscopic electroresection or laser resection.
However, bladder cancer is characterized by a high recurrence rate, but for patients with recurrence, 80%~90% can achieve curing effect
through repeated surgery and postoperative perfusion therapy.

Bladder cancer can be divided into non-muscle-invasive bladder cancer and muscle-invasive bladder cancer
.
Currently, the preferred clinical treatment for non-muscle-invasive bladder cancer is transurethral resection of bladder tumour plus postoperative adjuvant intravesical perfusion (chemotherapy and immunotherapy).

The preferred treatment of muscle-invasive bladder cancer is radical cystectomy plus pelvic lymph node dissection
.
Transurethral resection of bladder tumors not only has a diagnostic effect, but also has a therapeutic effect, and radical treatment
can be carried out according to the pathological characteristics of the tumor.

At present, there is insufficient evidence for the effectiveness of bladder cancer screening, and bladder cancer screening
is not recommended for the general population.
However, for high-risk groups, it is recommended to perform urine cytology 1~2 times a year, and pelvic ultrasound, cystoscopy, pelvic CT, and MRI can be performed
if necessary.
