Want to see bladder cancer pictures from cystoscopy? You can see them below of this article , but let’s learning what bladder cancer firtst. The urinary bladder is a muscular organ, lined inside with abundant mucous membrane. In the majority of cases, bladder tumors develop from this mucous membrane and often grow for a long time unintentionally. In Austria, approximately 1,600 patients are newly affected by bladder cancer every year, while men are affected four times more frequently than women. The median age of the disease for men is 69.1 years; women are ill with an average of 73.4 years.
After prostate cancer, bladder cancer is the second most common tumor in the field of urology, but in all cases the fourth frequency in men and the eighth in women.
Causes and risk factors
The exact causes for the development of bladder cancer are not known. Nevertheless, there are favorable risk factors which can contribute to the development of the disease.
- Smoking: The risk of developing bladder cancer increases with the duration of smoking and the number of smoked cigarettes.
- Chronic inflammation of the urinary bladder (by bladder stones or permanent catheters) can promote the development of a urinary bladder carcinoma.
- In areas such as Africa, Asia and South America, bilharziosis, an infectious disease caused by larvae of parasites in warm waters, is one of the most common causes of bladder cancer.
- Age: The risk of becoming ill increases with the age of life. Bladder carcinomas are predominantly found after the age of 60.
- Gender: Men are significantly more affected than women.
- Drugs: Taking high doses of the active substance cyclophosphamide can promote cancer risk.
- Occupational exposure: In Europe, approximately 10% of the urinary bladder tumors are caused by substances exposed to people in their working lives. Workers in the rubber, chemical and leather industries as well as hairdressers, metalworkers, printers, painters, textile workers and truck drivers are at increased risk. Certain aromatic amines act as a cause of cancer. They come as residues of plant protection products in food as well as ingredients of cosmetics and hair dyes. Aromatic hydrocarbons in hard coal, tobacco, soot, car exhaust gases, asphalt, diesel oil, diesel exhaust gases, gasoline products, lacquers and impregnations are harmful substances that can cause cancer.

Bladder cancer often remains unobserved for a long time due to lack of clear symptoms.
- Visible blood in urine (macrohematuria): The earliest symptom is painless blood flow in the urine. They occur in 68-97.5% of all patients and are caused by bleeding from the urinary bladder. In contrast to simple urinary bladder infections however, lacking symptoms such as pain or fever are missing.
- Blood not visible in the naked eye (microhematuria): The blood in the urine is only present in such small amounts that it is not visible, but can only be detected in the laboratory.
- increased urge to urinate
- frequent urination
- Difficulty in watering
- If the tumor is already advanced, flank and bone pain are added. In many cases, there is also a considerable weight loss.
1. Non-muscle invasive urinary bladder carcinoma
Three-quarters of all patients have a so-called “superficial” or “non-muscle invasive” bladder carcinoma at the time of diagnosis. At this stage, only the inner lining of the bladder is affected, but not the underlying muscle layer. At this early stage, patients have a good prognosis. The risk of recurrence of the tumor – after surgical removal – is 50-70% in the first five years. Nevertheless, the superficial bladder carcinoma can be kept under control by regular controls and re-resection.
2. Muscular invasive urinary bladder carcinoma
In approximately one quarter of all patients, the urinary bladder carcinoma has already penetrated into the muscle layer at the time of the diagnosis, or has developed in the course of a superficial tumor disease. The 5-year survival rate is between 20% (with lymph node involvement) and 80% depending on the tumor stage. Metastasis in the lungs, liver or skeleton is significantly worse. With systemic chemotherapy, the mean survival probability is slightly above one year.
