The bladder is a hollow, muscular, balloon-like organ with a flexible wall. It is situated in the pelvis and collects and stores urine. Bladder cancer starts in the bladder lining (urothelium) but can then spread to deeper bladder layers.

The urinary tract

  • The kidneys produce urine. This is transferred to the bladder by thin tubes called ureters.
  • A urine-proof lining (urothelium) covers the inside of the bladder and stops urine going back into the body.
  • The lining cells are called urothelial or transitional cells.
  • When the bladder is full, its muscles contract and push urine into the urethra.
  • In women, the urethra is a very short tube that ends just in front of the vagina.
  • In men, the urethra is longer. It passes through the prostate gland and ends at the tip of the penis.

Bladder cancer risk

  • Worldwide, bladder cancer is the tenth most common cancer.
  • It is four times more common in men than women, however it's often diagnosed later in women leading to a lower overall survival rate.
  • It usually affects older adults, but can occur at any age.
  • It is most common in men aged 55+ years.
  • It is rare in people aged less than 40 years.

Bladder cancer often recurs

  • Most bladder cancers are diagnosed at an early stage, when they are highly treatable.
  • Even early-stage cancers are likely to recur.
  • Patients who survive bladder cancer require follow-up testing for many years after their first treatment.

Bladder cancer: superficial or invasive?

  • The bladder wall has several layers from inside to out (see Diagram):
    • Urothelium.
    • Lamina propria - a thin layer of connective tissue beneath the urothelium.
    • Muscularis propria - a muscle layer.
    • Fatty connective tissue.
  • Almost all bladder cancers start in the urothelium.
  • If bladder cancer affects only the urothelium it is called superficial.
  • Bladder cancers may spread into deeper bladder layers; they are then more difficult to treat.

If bladder cancer spreads to the muscle layer it is called invasive.

Detecting bladder cancer

Detecting bladder cancer early helps patients receive the care they need before their condition becomes serious. As a result, it's essential to consult a medical professional if you notice any symptoms of bladder cancer, such as haematuria, or blood in the urine.

If You're Concerned About Bladder Cancer, Ask Your Doctor About Cxbladder

Cxbladder is a suite of easy-to-use and non-invasive tests designed to help rule out urothelial bladder cancer, the most common form of the disease, in patients experiencing blood in urine (haematuria) and to monitor for recurrent disease in those who have been treated for non-muscle invasive bladder cancer. 

Cxbladder is an advanced genomic test that analyses five biomarker genes. The test reduces the need for further invasive procedures when patients are at a low risk of disease. With a single urine sample, Cxbladder delivers exceptional performance and meaningful results and can provide peace of mind and inform a positive treatment direction for patients, caregivers and doctors.
