Occupational medicine plays a key role in protecting the health of workers, particularly in preventing occupational diseases, including urologic cancers. These neoplasms, which mainly affect the kidneys, bladder, prostate and urinary tract, can have an occupational origin as a result of prolonged exposure to carcinogens present in certain work environments. Effective prevention requires an integrated approach between health surveillance, risk assessment and health promotion.

Among urological cancers, bladder cancer is the most frequently related to occupational causes. Its incidence is significantly increased in workers exposed to substances such as:

- Aromatic amines (found in chemical, textile and rubber industries);
- Polycyclic aromatic hydrocarbons (PAHs) (typical of activities related to smelters, asphalt and aluminum production);
- Organic solvents such as trichloroethylene, used in industrial metal degreasing or cleaning processes.

Kidney and prostate cancer, while less frequently associated with occupational causes, can also be linked to exposures to heavy metals, pesticides and other chemicals.

Prevention begins with an accurate assessment of the risks present in work environments. Occupational medicine figures, together with safety managers and environmental specialists, must:

- Map exposures to potential carcinogens;
- Classify exposed workers according to duration and intensity of contact with hazardous agents;
- Adopt technical and organizational measures to reduce or eliminate sources of exposure.

Periodic health surveillance is a key tool for early detection of signs of urological changes. It includes:

- Urine cytology examination;
- Targeted urological examinations;
- Specific assessments for at-risk workers (e.g., urine chemistry/physical examination, ultrasound).

In case of symptoms such as hematuria (presence of blood in the urine), it is essential to initiate diagnostic investigations immediately.

Prevention also comes through information and training for workers, who must be made aware of the risks associated with the substances used and the good practices to be adopted, such as:

- The proper use of personal protective equipment (PPE);
- Adherence to safety protocols;
- Adherence to screening programs and healthy lifestyles, such as avoiding smoking, which is a known risk cofactor for bladder cancer.

Prevention of urologic cancers in the occupational setting is possible and necessary. Effective occupational medicine is one that does not just manage the disease, but acts first, preventing exposure and promoting a culture of safety and well-being. This is the only way to ensure a healthier work environment and a concrete reduction in cancer risk among workers.
