The Causes of Bladder Cancer
The bladder is located below the lower abdomen and above the pubic bone. Its function is to store and discharge urine from both kidneys.
The causes of bladder cancer are related to industrial products, pigment dyes, drugs, smoking, urinary tract infections, cystitis, and parasites in the bladder. In addition, certain metabolites in the body and the genes of the cells themselves may also cause bladder cancer.
The symptoms of bladder cancer
The most typical symptom of bladder cancer is hematuria, and it is usually painless. But unless it is severe hematuria, it can be seen with the naked eye, and mild hematuria can only be examined under a microscope.
