Dr An-Chi Lo and colleagues from Egypt examined the epidemiology of pancreatic cancer in Egypt.
The team of doctors obtained detailed information on smoking, occupational, medical, and reproductive histories from 194 pancreatic cancer cases and 194 controls.
The team found that smoking cigarettes alone or in conjunction with other smoking methods was associated with an increased risk.
|Passive smoking increases the risk for pancreatic cancer|
The team noted that passive smoking was also a significant risk factor.
The doctors elevated the risk of pancreatic cancer among subjects exposed to pesticides.
A prior diagnosis of diabetes mellitus for a period of 10 years was associated with higher risk.
The doctors observed that for women, having 7 or more live births and lactating for 144 months or longer were associated with a reduced risk.
No association was found between family history, allergy, or obesity and pancreatic cancer in Egypt.
Dr Lo's team concluded, "Multiple tobacco consumption methods, passive smoking, pesticide exposures, and diabetes are associated with an increased risk for pancreatic cancer."
"Prolonged lactation and increased parity are associated with a reduced risk for pancreatic cancer."
