'Half a glass of wine every day' increases breast cancer risk

Further evidence has emerged of the link between alcohol consumption in women and an increased risk of breast cancer.
According to a report from the World Cancer Research Fund, half a glass of wine or a small beer a day increases the risk of breast cancer.
It also backs up research showing that regular intensive exercise can reduce the risk of the disease.

But is it really that simple?

Breast cancer is by far the most common cancer in women in the UK with one in eight women developing the disease during their lifetime.
But scientists say they can't explain why the cancer occurs in some people and not in others.
There are numerous causes and lots of factors to take into account, including lifestyle, hormone levels and other medical conditions.
Basically, it's a complex picture and there's no point focusing on one factor only.

So what are the risk factors for breast cancer?

For a start, there are some factors you cannot control such as your sex, age, height, genes and when you started your periods.
Being a woman, over 50 and past the menopause, and having a history of breast cancer in your family, all increase your risk of getting the disease.
Being tall and starting periods before the age of 12 are thought to increase the risk too.
Cancer Research UK lists 18 different factors which could cause breast cancer to some degree. Alcohol is only one of them.

What does this report say?

It says there are ways women can lower their risk of breast cancer by focusing on factors they can control, like diet, weight and exercise.
After analysing more than 100 studies that examined the medical history of 12 million women, the report backs up current advice to be aware of alcohol consumption.
The report found evidence that drinking an extra small glass of wine every day (10g of alcohol) increases a woman's risk of breast cancer after the menopause by 9%.

What does that really mean?

It means that in a group of 100 women, around 13 would be likely to develop breast cancer anyway.
And if they all drank an additional small glass of wine every day, one extra case might develop among the original group.
