Most often, neoplasms from the organs of the genitourinary system occur in the prostate, bladder and kidneys.
World statistics claim that prostate cancer is the most common in the world, but Armenia's statistics contradict world data. Bladder cancer is more common in our country.

Smoking has been proven to be one of the main factors contributing to the development of bladder cancer. The fact is that with age, the prostate gland in a man inevitably increases and from the age of 45-50 it can interfere with urination and, as a result, the bladder does not empty completely. Tumor substances contained in tobacco enter the bloodstream with smoke, then are filtered in the kidneys and
enter the bladder with urine. In patients with residual urine (incomplete bladder emptying), these oncogenic agents continue to negatively affect the bladder wall and lead to bladder cancer.

In general, most tumor formations in the initial stages do not cause any complaints, and patients go to the doctor mainly in cases where this formation is common. Small tumors in the bladder also do not cause any complaints. With an increase in size, the formation can be damaged, in which case bleeding will occur, which, as a rule, is transient. After the bleeding stops, patients associate this phenomenon
with cold, active movement, or some other reason and do not pay attention.

However, it is very important to take this complaint very seriously. Bleeding can occur with malignant and benign tumor diseases of the kidneys, urinary tract, prostate. (bladder cancer)

Hematuria is a dangerous clinical sign, in which case it is necessary to conduct an examination and find the cause of bleeding. First of all, ultrasound is performed, if any tumor-like formation is detected, computed tomography (CT) or magnetic resonance imaging (MRI) is performed. CT examination is mainly carried out with intravenous contrast agent, resulting in improved visualization of tissues. MRI
can be used with or without a contrast agent.

MRI is mainly used to assess the spread of prostate cancer – whether the tumor is in the prostate gland or outside it, as well as to assess the condition of the skeletal system and lymph nodes.
