Healthcare workers (HCWs) are exposed to a variety of health hazards in their daily duties, including classical hazards such as physical, chemical, and biological dangers, as well as modern hazards like shift work, stress, and violence during patient care. A 14-year retrospective cohort study in Thailand found that the risk of leukemia was higher than expected among healthcare workers, suggesting that physicians may have an increased vulnerability to cancer compared to the general population. The study also highlighted the absence of occupational health systems, inadequate control measures for carcinogen exposure, and the need for improved health promotion within hospitals to protect HCWs from work-related health problems. These findings emphasize the importance of occupational health services and safe work practices to minimize the incidence of cancer among hospital workers.

Healthcare workers are exposed to classical hazards such as physical, chemical, and biological dangers
Healthcare workers are exposed to classical hazards, including physical, chemical, and biological dangers. These dangers are unique to hospitals as a workplace, encompassing a broad spectrum of occupations and exposing workers to a variety of health hazards or health risks.
Physical Hazards
Healthcare workers can be exposed to radiation, noise, and slips and falls. Time pressure, long working hours, shift work, and lack of support are also factors that can cause harm to a healthcare worker.
Chemical Hazards
Chemotherapeutic drugs have been classified as carcinogens, and exposure to them is a work hazard. Other chemical hazards include sterilants, toxic drugs, pesticides, latex, and laboratory chemicals and reagents. The use of chemical sterilants, such as ethylene oxide (EtO), is important for preventing healthcare-associated infections in patients, but they can be hazardous to healthcare workers. Additionally, long-term exposure to halogenated anesthetics may cause harmful reproductive effects and cancer.
Biological Hazards
Biological hazards include exposure to bloodborne pathogens and tuberculosis. Healthcare workers are also at risk of exposure to antineoplastic drugs, which are used to treat cancer and other medical conditions.
To prevent cancer among healthcare workers, hospitals should emphasize occupational health services and health promotion to decrease the incidence of cancer. Systematic control measures should be implemented to minimize carcinogen exposure, and safe work practices should be promoted.

Chemotherapeutic drugs are a work hazard, and many are classified as carcinogens
Chemotherapeutic drugs are a well-known work hazard for healthcare workers, with many classified as carcinogens. The International Agency for Research on Cancer (IARC) has reviewed and classified many chemotherapeutic drugs as carcinogens. These drugs are known to cause cancer in humans, with no safe level of exposure. The development of secondary cancers in patients undergoing chemotherapy is a documented side effect, with leukemia being the most frequent adverse outcome. Other secondary malignancies, such as bladder cancer and lymphoma, have also been observed.
Healthcare workers, particularly those working in the chemotherapeutic unit, are at risk of exposure to these hazardous drugs. This exposure can occur during the shipping, transport, distribution, compounding, administration, or waste disposal stages of the drug's life cycle. The inherent toxicity of chemotherapeutic drugs poses a significant risk to the health and safety of healthcare workers, with an increased risk of leukemia and other cancers. This risk is heightened for oncology nurses who handle these drugs regularly.
To mitigate this work hazard, guidelines have been established by professional organizations and government agencies to ensure the safe handling of chemotherapeutic drugs. These guidelines emphasize the importance of implementing a hierarchy of controls, including engineering controls, administrative controls, work practice controls, and personal protective equipment (PPE). Engineering controls, such as closed-system transfer devices (CSTDs), aim to minimize direct contact with hazardous drugs. Administrative controls include training and education, hazard communication, and medical surveillance. Work practice controls involve immediate spill cleanup and the use of absorbent pads to reduce exposure.
In addition to these controls, the proper use of PPE is crucial. A standard or universal precautions approach should be applied when handling hazardous chemotherapy drugs, as there is no known safe level of exposure. The use of exhausted enclosures, procedures to avoid personal exposure, and the proper disposal of contaminated PPE are also essential to minimize the risk associated with these carcinogenic drugs.
The implementation of these guidelines and controls aims to protect healthcare workers from the hazardous effects of chemotherapeutic drugs and reduce their vulnerability to cancer.

Hospitals expose workers to a variety of health hazards and risks
One significant risk is carcinogen exposure. Chemotherapeutic drugs, for example, have been classified as carcinogens, and hospital workers in the chemotherapeutic unit have been found to have a higher Standardised Incidence Ratio (SIR) than those in other working areas. However, it is important to note that one study did not find a significantly higher incidence rate of cancer among hospital workers in general when compared to the general working population. Nonetheless, the risk of leukaemia was found to be higher than expected among healthcare workers, suggesting that their working environment may play a role in this increased risk.
Healthcare workers are also at risk of exposure to classical hazards such as physical, chemical, and biological dangers, as well as more modern hazards like shift work, stress, and violence experienced during patient care. Systematic control measures to minimise carcinogen exposure and promote safe work practices are essential to protect the health of hospital workers. This includes providing proper personal protective equipment (PPE), vaccinations, and periodic risk-based examinations.
In addition to external hazards, hospital workers may also face increased cancer susceptibility due to individual health behaviours such as smoking, drinking alcohol, and imbalanced food consumption, which can lead to obesity. To prevent cancer among hospital workers, occupational health services and health promotion initiatives should be emphasised, and further studies should identify specific risk factors associated with particular occupations and types of cancer.

Male physicians may be more susceptible to cancer due to behaviours like smoking and drinking
Healthcare workers (HCWs) are exposed to a multitude of health hazards and risks in their daily duties. Hospitals are unique workplaces, with a broad spectrum of occupations and complexities. A 14-year retrospective cohort study in Thailand found that the risk of leukaemia was higher than expected among healthcare workers, and physicians may have an increased risk of cancer compared to the general population.
Male physicians, in particular, may be more susceptible to cancer due to behaviours like smoking, drinking, and imbalanced food consumption, which can lead to obesity. Smoking is a significant risk factor for cancer, as poisons in cigarette smoke can weaken the immune system and damage or alter a cell's DNA, making it harder to stop the growth of cancer cells. Lung cancer is the leading cause of cancer death, with nearly 9 out of 10 cases caused by smoking or secondhand smoke exposure. Quitting smoking lowers the risk of 12 types of cancer, including lung, larynx, oral cavity, and pancreas.
Alcohol consumption is also a known carcinogen, increasing the risk of cancers of the oral cavity, pharynx, larynx, oesophagus, and liver. Even light drinking can increase cancer risk, and the more someone drinks, the higher the risk becomes. For example, women who have one drink per day have a higher risk of breast cancer than those who drink less frequently.
In addition to these behavioural risk factors, male physicians may also be exposed to specialty-specific occupational carcinogens, such as chemotherapeutic drugs, which have been classified as carcinogens by the IARC. Hospitals should emphasise occupational health services and promote safe work practices to decrease the incidence of cancer among their staff.

Hospitals should emphasise occupational health services to reduce cancer incidence
Hospitals are complex workplaces that encompass a wide range of occupations and expose workers to various health hazards and risks. Healthcare workers (HCWs) are valuable members of society who require a costly and high level of education. However, they are also at an increased risk of developing cancer due to their work environment. A 14-year retrospective cohort study in Thailand found that the risk of leukaemia was higher than expected among healthcare workers, suggesting a potential link between the job and cancer incidence.
The working environment, especially in hospitals, plays a significant role in influencing the health of workers. Healthcare workers are at risk of exposure to classical hazards such as physical, chemical, and biological dangers, as well as modern hazards like shift work, stress, and violence during patient care. In addition, chemotherapeutic drugs have been classified as carcinogens, and working with them can increase susceptibility to cancer.
To address this issue, hospitals should emphasise occupational health services and health promotion for HCWs to reduce cancer incidence. This includes implementing systematic control measures to minimise carcinogen exposure and promoting safe work practices. For example, providing vaccinations, periodic risk-based examinations, and proper personal protective equipment can help reduce the risk of cancer among physicians.
Furthermore, hospitals should also focus on identifying other risk factors for cancer among HCWs, such as individual health behaviours. This can include addressing behaviours such as smoking, drinking alcohol, and imbalanced food consumption, which may lead to obesity and increase susceptibility to cancer. By offering educational programmes and support services, hospitals can empower HCWs to make healthier choices and reduce their risk of cancer.
In conclusion, hospitals play a crucial role in protecting the health and well-being of their workers. By emphasising occupational health services and implementing preventive measures, hospitals can effectively reduce the incidence of cancer among HCWs and create a safer work environment.
