The bladder, which has a flexible structure, is the part where urine accumulates. Urine is stored in the bladder and is expelled from the body through the urethra. Muscles that allow the bladder to stretch according to the amount of urine are also involved in this emptying process.
Uncontrolled proliferation of cells in the bladder for different reasons is called bladder cancer. Cancerous cells generally consist of uroepithelial cells in the urinary bladder and may spread to muscles, lymph nodes, surrounding tissues and organs in the future. The tumor can affect the excretory system as well as the bladder.
The tumor can be benign (benign) or malignant (malignant). According to the studies, 95% of the total cases are malignant and 5% are benign tumors. However, it can often be treated before it reaches the stage of metastasis. Bladder cancer is also more likely to recur. This disease is also one of the most common types of cancer in the excretory system.
Important risk factors for bladder cancer include age, gender, and race. It is observed that this type of cancer is more common in individuals over 50 years of age, especially in advanced age, compared to younger individuals. It has also been found that bladder cancer is up to 4 or 5 times more common in men than in women. Although bladder cancer is the 7th most common type of cancer in men, mortality rates are the opposite; The death rate from bladder cancer in women is higher than in men. Researches also reveal that most individuals with bladder cancer are members of the white race.
