Paramedics’ Excess Cancers Linked with Workplace Exposures

“Paramedics share many of the same exposures as firefighters and police as they respond to calls in private homes, public spaces and emergency incidents such as fires, building collapses, motor vehicle incidents and also natural disasters.” – Dr. Jeavana Sritharan
Paramedics Are Also Health Care Workers.
Most occupational breast cancers in women associated with night shift work occur among workers in the health care industry. These cancers also occur among workers in the accommodation and food services, trade, and manufacturing sectors.
Shift work at night (generally between the hours of 12 a.m. and 5 a.m.) disrupts circadian rhythms, or the internal biological ‘clock’ that generates the sleep-wake cycle in humans.
Circadian disruption suppresses melatonin production, disrupts sleep patterns and food digestion, and de-regulates genes involved in cancer pathways.
The International Agency for Research on Cancer classifies night shift work as a probable carcinogen (IARC 2A).
