Understanding Bladder Cancer
Bladder cancer is a malignant tumor in the urinary bladder. The most common type of bladder cancer is urothelial carcinoma. Here you can learn more about the symptoms, risk factors and prevention of bladder cancer.
Bladder cancer develops when cells of the urinary bladder start to divide and grow more rapidly than usual. As more cancer cells are generated, they form a tumor, which can grow through the layers of the bladder and spread to other areas of the body. Bladder cancer is one of the most insidious types of cancer, as it is often discovered only by chance and at a stage when it is almost too late for successful treatment. If detected early, bladder cancer has a chance of cure of over 90%. Despite new discoveries and improvements in the care of people with bladder cancer, there’s still a significant need for medical advancement in this area.
Bladder cancer is the 10th most common cancer and the 13th most common cause of cancer death in the world
Every year, about 1’280 people in Switzerland are diagnosed with bladder cancer and about 570 die of it.
Around 573’000 new cases of bladder cancer were recorded worldwide in 2020, about 212’000 patients died of it.
Bladder cancer occurs mainly in older adults. Of those affected, about 75% are men and 25% are women.
Signs and Symptoms
Bladder cancer often causes no specific symptoms for a long time. Affected people may experience the following symptoms or signs:
- Blood in the urine
- Frequent urination
- Pain or burning during urination
- Feeling the need to urinate, even if the bladder isn’t full
- Having to get up to urinate many times throughout the night
- Lower back pain on one side of the body
Bladder Cancer Risk Factors
One of the main risk factors is smoking. Experts estimate that about 30% to 70% of all bladder cancer cases result from smoking. Smokers are 4 to 7 times more likely to develop bladder cancer than nonsmokers.
Other Risk Factors for Bladder Cancer include:
- AGE – being older than 65 years
- GENDER – being male
- CERTAIN CHEMICALS – frequent and prolonged contact
- CHEMOTHERAPY/RADIOTHERAPY in the pelvic area
- CHRONIC CYSTITIS – inflammation of the bladder
- MEDICAL HISTORY – higher risk if someone has already had bladder cancer
Bladder Cancer treatment
There are several options for the treatment of bladder cancer:
- Local surgical therapy
- Local drug therapy
- Surgical removal of the bladder, called cystectomy
- Radiation therapy
- Systemic drug therapy: chemotherapy or immunotherapy
If metastases have already formed, the prognosis for a permanent cure is unfavorable in most cases. However, the progression of the disease can be delayed.
Prevention of Bladder Cancer
There is no guarantee to prevent bladder cancer. But there are some factors that can help lower the risk.
- Don’t smoke.
- Limit exposure to certain chemicals in the workplace.
- Drink plenty of liquids! Drinking a lot of fluids – mainly water – might lower the risk of bladder cancer.
- Eat lots of fruits and vegetables.
