In this period dedicated to awareness of bladder cancer, let’s explore a potentially revealing symptom for early detection of this disease which affects between 13,000 and 20,000 individuals in France each year.
The unrecognized symptoms of dreaded bladder cancer remain a reality for the majority of French people. According to a survey by the Merck-Pfizer Alliance, a quarter of French people are unaware of at least one symptom of this insidious disease. However, between 13,000 and 20,000 new cases are diagnosed each year in France, making this cancer the 7th most common.
Mainly prevalent in men (more than 80% of cases) and generally affecting around the age of 50, bladder cancer has a 5-year survival rate of 80% if detected early, but only 5% if diagnosed metastatic. So, knowledge of the symptoms that can facilitate early detection is crucial. As part of Bladder Cancer Awareness Month in May, the French Urology Association (AFU) and the Cancer Bladder France patient association are joining forces to provide information on the signs to watch out for.

Blood in the urine: an early symptom to watch carefully
The presence of blood in the urine, called hematuria, is an early symptom seen in 80% to 90% of bladder cancer cases. Although there is no validated systematic screening method for this disease, specialists emphasize that hematuria during urination should be given special attention and medical consultation. Recurrences of cystitis, urinary tract infections in the bladder, as well as urination disorders should not be overlooked and require medical evaluation.
Smoking is a major factor in more than 50% of bladder cancer cases in men and about 40% in women, according to the National Cancer Institute (INCa). However, other external factors can also contribute to its development. Occupational exposure to chemicals such as aromatic amines and polycyclic aromatic hydrocarbons may play a role, accounting for about 5% of cases, according to L’Assurance Maladie.
In addition, the presence of arsenic in certain mineral waters, certain diseases and treatments can also influence the development of bladder cancer. By adopting a healthy lifestyle and being aware of the potential risks, it is possible to reduce the chances of developing this disease and improve the prospects for treatment and survival.
