Can bladder cancer be prevented?
The best way to prevent bladder cancer is to avoid exposure to agents that cause the disease. People who don't smoke are three to four times less likely to get bladder cancer as compared to smokers. Continuing to smoke after the diagnosis of bladder cancer portends a poorer outcome and increases the chance of the disease coming back after treatment. Avoidance of occupational exposure to cancer-causing chemicals such as aniline dyes may also be important. Despite research in this area no medication or dietary supplement has been conclusively demonstrated to decrease the risk of bladder cancer in normal individuals.
Where can people find more information on bladder cancer?
A number of online resources are available for bladder cancer patients to gain more insight into this disease and its management. Bladder Cancer Advocacy Network (http://www.bcan.org) is one such resource which provides a downloadable patient information handbook and links to patient support groups.
The National Cancer Institute (http://www.cancer.gov/cancertopics/
types/bladder) also provides bladder cancer information.
The European Organisation for Research and Treatment of Cancer (http://www.eortc.be/tools/
bladdercalculator) features a calculator which predicts the chances of recurrence and progression of superficial bladder cancer after initial treatment on the basis of certain tumor characteristics.
What research is being done on bladder cancer?
Bladder cancer is a topic of intense scientific research currently. Basic science research is focused on finding and studying the genetic alterations (or changes in the human DNA) that predispose to bladder cancer in the hopes to discover new medications and treatments for curing the disease. Other areas of research include the following:
- Newer molecular diagnostic tests to detect bladder cancer thereby avoiding the need for invasive tests like frequent cystoscopy examination
- Targeted therapy acts on genetic pathways responsible for bladder cancer as the next generation of chemotherapy for the disease.
- Newer surgical techniques, such as robotics, have been incorporated to improve precision and accelerate patient recovery after bladder cancer surgery.
- Stem cell research for creation of urinary diversion during radical cystectomy without the need for intestinal segments.
This field is likely to see significant advances in the years to come and hopefully would provide effective treatment strategies and hope for the millions of bladder cancer patients worldwide.
