Women have always been warned on the dangers "smoking pregnancy" as it causes birth complications. Now research has also proved that babies born to women who smoked during pregnancy are at a significant higher risk (five times, to quote the study) of developing childhood cancer.
Researchers at the Cancer Institute NSW found that leukemia, brain, kidney and eye cancers were common in kids whose mothers smoked during pregnancy.
They found that babies admitted to neonatal intensive-care units run the greatest risk of developing cancer, reports the Daily Telegraph.
They are 2.7 times more likely to develop the disease and five times at risk of kidney cancer.
The researchers linked the records of all births in NSW between 1994 and 2005 with cases of cancer in children during the same period.
Of the 1.05 million recorded births, there were 948 cases of childhood cancer.
According to assistant Health Minister Jodi McKay, the research was a 'smoking gun'.
