Does alcohol increase of breast cancer?

Yes, Alcohol does substantially increase the risk of Breast cancer.

Very few people seem to be aware of the risks.

Previously it was thought that heavy drinking is responsible for harmful cancer effects.

But studies from U.K and U.S.A have subsequently shown that even light to moderate drinking can increase the risk of breast cancer.

A very large study involving more than 1,250,000 middle-aged women in the United Kingdom ( enrolled in the Million Women Study) showed that “Low to moderate alcohol consumption” in women increases the risk of breast cancer and certain other cancers.

In a study involving more than 88,000 women from United States, also showed that light to moderate drinking increases the risk of breast cancer.

So keep counting the alcohol units during the festive time.

Dietary advice: take it with a pinch of salt

Official dietary advice as well as various “Diets” promoted by various celebrities tend to be very prescriptive. They often give the impression that the evidence behind everything they promote is very clear cut.

But truth is far more murkier ( I might say more “mish mash “).

A new study analysis of old data comes to a different conclusion about “red meat”. This is in fact not surprising as the evidence for various Dietary guidelines and “Diets” are not usually robust and watertight and involves lot of assumptions.

What is the take home message:

Eat “everything you like” in moderation and try to make it as balanced as possible with substitutes for things you avoid !!

Avoid processed food as much as possible and eat fresh.

Don’t be surprised if the next two studies on this topic reach three different conclusions.
