Smoking, booze during pregnancy may raise child's cancer risk

London, Sept 19 (ANI): Whether an expecting mother smokes, drinks or is overweight - all play a key role in determining the risk of her child developing cancer, says a new study.

Professor Ricardo Uauy, an adviser to the United Nations and the World Health Organisation, said that although cancer risk is usually associated with people's genes and their behaviour as adults, women's lifestyles before getting pregnant and while carrying their baby have a major impact on whether their child will develop the disease.

"Someone's risk of developing cancer starts from before the time of conception. The risk factors are already operating in the mother's eggs before conception," The Guardian quoted Uauy as saying.

"Yes, cancer is a genetic disease, but your chances of getting cancer are affected by the environment in which you live. So it's not just about if you smoked from the age of 12. But did your mother smoke? What was the water like that she drank? Is she exposed to toxins such as dioxins, which are found in the environment, and did she pass them on to her baby through her breast milk?" he added.

Uauy advised that women should stop smoking before they start trying to conceive, because that increases the chances of the child having a low birth-weight. They should not drink alcohol, take an iron tablet if necessary, and ensure they get at least 400mg of folate every day.

Children born lighter than average often then put on weight quickly, but in the form of fat rather than muscle, and develop fat around the middle, which raises cancer risk.

"Mothers-to-be only need to consume an extra 150 calories a day during the nine months of pregnancy, and should not 'eat for two'," stressed Uauy.

Babies should not eat any solid food until they are six months old, nor be given any sweet drinks such as fruit juices in case that encourages an appetite during childhood for sugar-laden drinks, which promote weight gain. (ANI)
